Making pure Deuterium gas and tasting Heavy Water!

Making pure Deuterium gas and tasting Heavy Water!

Hello everyone, in this video I am going
to tell about heavy water and its properties and I am going to try to extract pure deuterium from it. In case water all over the world consists not of dihydrogen monoxide alone. This element has three isotopes, protium or as it is also known hydrogen, deuterium and tritium. Tritium or as it is also known as ultra heavy hydrogen is an unstable isotope and that is why it’s
concentration in water is negligibly small, it decays into helium-3
releasing an electron and antineutrino. Release of electrons can irradiate the luminophore layer made of zinc sulfide. This same property of tritium is used in tritium charms, to which a small amount of radioactive tritium isotope is soldered.
Besides unstable tritium there also exists deuterium which is also known as heavy hydrogen. In contrast to tritium it is a stable isotope and occurs naturally in regular water in the form of deuterium oxide it’s
concentration is water is very small. Human body isn’t an exception either. Roughly 70% of it is water including heavy water. If you weigh about 75 kilograms, your body contains roughly 5.5 milliliters of heavy water or deuterium oxide which is within normal limits. If to take regular ocean or sea water and start carrying out a lengthy process of electrolysis or distillation of it, it can be enriched with heavy heavy water or in other words its concentration will increase. During electrolysis regular light hydrogen escapes whereas the heavier deuterium atoms remain in the solution. During distillation heavy water also remains in the solution because its boiling point is one degree Celsius higher than that of water. However, such methods are quite pricey at the beginning stages, that is why a more effective Girdler sulphide method is employed at the initial stage. This method is based on isotope exchange between water and hydrogen sulfide.
Alright let us move from theory to practice and study properties of heavy water. It looks almost exactly like regular light water. Basically, this is where similarities end. It is for a reason that this water was named heavy. Its density is 10,6% higher than that of regular water. To check that, first I measured out 50 milliliters of regular distilled water into a beaker, besides when I weighed it, the mass turned out to be a bit smaller than 50 milliliters because the temperature in the room was 25 degrees Celsius instead of 4 degrees. Let me remind you that water’s density is 1 gram per cubic centimer only when its temperature is 4 degrees Celsius. I poured 50 milliliters of heavy water into another beaker. As we can see 50 milliliters of heavy water is 5 gram heavier than regular distilled lighter water. Besides having different boiling temperature and density, heavy water is also more viscous than regular water. This property can be observed even with the naked eye. When I stir water in both beakers, the solution of deuterium oxide to the left behaved slightly differently. It seemed that it was slightly syrup like. To better demonstrate you this effect I decided to fill one syringe with 5 milliliters of regular water and the
other syringe with 5 milliliters of milliliters of regular water and the other syringe with 5 milliliters of heavy water and poured out the liquids back into their beakers. Comparing these two videos we can see that bubbles in the right hand beaker form more actively than in the left hand beaker.
One more difference between deuterium oxide and hydrogen oxide is that heavy water has a slightly lower melting point. For this experiment I have filled two beakers with an equal amount of water, one with heavy water, the other with regular water. I have dyed distilled water red and heavy water blue in order to better distinguish them. Two hours later was
liquid froze in the freezer. If you touch one cube of ice with the other one
they’ll freeze to each other. That happens because the melting point of
heavy water is 4 degrees higher than that of hydrogen monoxide. Because of
this difference the blue cube freezes to the red cube because both cubes have
reached zero melting points and the heavy water sticks to the colder ice
cube made of regular water. That’s not all, these two ice cubes have different
densities that is why if you put them into a beaker with regular water, the ice
cube made of regular water will float where is the ice cube made of heavy
water will sink. If you ever say that ice floes on the surface of water you should
clarify what ice is meant. By the way it was quite interesting to watch how an ice
cube of heavy water was melting in a container with regular water. Bubbles and
streams of liquid surfaced. Bost probably density also changed, as a result of
mixing over regular water and heavy water. Now we have considered physical
properties of heavy water, now let us see how different chemical properties of
deuterium have is from hydrogen. First we need to obtain it. I have put together
such a device, I even had to borrow silica gel litterre from my cat, it absorbs
water including heavy water which can later be
used again. I’ll obtain pure deuterium
using a chemical reaction between heavy water and metallic calcium. The reaction
between heavy water and calcium isn’t that different from the same reaction
with regular water. It also produces a lot of heat. The only difference is that
the reaction produces deuterium and calcium deuterium oxide instead of
hydrogen and calcium hydroxide the produced gas alone with water vapor is
streamed into a drain chamber with silica gel after that I feel a balloon
with obtained deuterium as many other light gases the eternal is lighter than
air and it also burns well just like hydrogen das these two footages show how
deuterium and hydrogen burn there seems to be a minor difference between the two
flames deuterium flame is a bit reddish on top where is the flame of pure
hydrogen is more consistent both deuterium and hydrogen flames produce a
lot of heat in near zero temperatures can reach up to 1600 degrees Celsius
such a heat can easily melt glass however there is a difference in
temperature based on quite author searches carried out in 1949 release of
energy or enthalpy to be precise during the reaction between deuterium and
oxygen is 16 percent smaller than during the reaction between hydrogen and oxygen
maybe that is a reason why the flame reaction of deuterium and oxygen
produces is colder that the flame hydrogen and oxygen produce such a
reaction however is almost never used modern day scientists are more
interested in Iranian nuclear reaction between deuterium items which produces
isotope helium-4 II without this reaction
life on Earth will be impossible because this very reaction plays off protostars
when they are not fully formed from molecular of clouds this reaction is
also takes place inside brown dwarfs besides the first time a local bomb ever
invented by the Americans was based on liquid deuterium it was also named a
liquid bond it was so big that it looked more like a cryogen plant rather than a
bomb that can be used in battle after running the reaction used for obtaining
deuterium I decided to obtain deuterated acetylene for that instead of metallic
calcium i put pieces of calcium carbide into the class after that i began adding
ropes of heavy water I collected the produce deuterated acetylene into a
balloon for comparison I filled another balloon with a regular acetylene
obtained from the reaction between calcium carbide and irregular water
first I ran a classic reaction of oxidation of acetylene with potassium
permanganate solution in this reaction the triple bond is acetylene molecule
breaks and oxalic acid is produced as a product of oxidation this reaction can
run for about 20 seconds 26 seconds to be precise now let us see how this same
reaction will run with deuterated acetylene at first sight it seems that
the speed of this reaction is the same but if the measure time will see the
tree action with deuterated acetylene runs roughly 5 seconds longer it can be
explained by the fact that the bond between carbon and deuterium is much
stronger that the bond between carbon and hydrogen probably that is the reason
over action with deuterated acetylene runs slower than with a regular
acetylene I noticed a similar difference when I said acetylene and deuterated
acetone on and compared to flames both experiments
were run in the same conditions I use the same syringe needle in both
experiments as a nozzle if the compare both footages we can see this irregular
acetylene flame is more elongated and it is longer that deuterated a settlin
flame i suppose the distance of bonds between deuterium and carbon plays a
significant role here affecting the temperature of the flame and also
formation of radicals inside the flame this turned out to be a pretty
interesting experiment getting back to the topic of heavy water there is one
interesting story about it during the Second World War
scientists were actively developing nuclear weapons energy Germany and Z
needed weapons-grade nuclear material for its production to obtain this
isotope uranium 238 8oz have to be bombarded with slow neutrons which they
absorb very well however neutrons need to be slowed down
either in pure graphite which the nicest didn’t have or in heavy water a huge
amount of energy was needed which is in as occupied Norway could abundantly
supply because there are a lot of waterfalls and places suitable for
construction of hydroelectric power plants heavy water was obtained using a
cheap method of electrolysis however thanks to the efforts of the Allied
forces the heavy water was never transported to Germany ferry whistle Oak
sent in 1943 on the lake team the advantage of reactors are on input heavy
water is that regular uranium can be used as fuel for them instead of
enriched uranium because heavy water absorbs fewer neutrons then lighter
water you will have to spend a lot of money on heavy water in the end I
decided to take the risk and take the heavy water I’ll try to compare
heavy water and odd drinking water which was passed for was
a filter as far I know deuterium oxide taste is sweet if we have watch the
channel Cody’s lab there he also tasted heavy water and say that it taste is
sweet so let’s check it out first I’ll try ordinary water for
comparison just plain water now I’m taking somewhere one milliliter
of heavy water I do not advise anyone to drink heavy water it’s dangerous but I
can I am a professional a little bit sweet hmm very strange this water has a
taste of plastic as it is stored in a plastic bottle by the way on the
internet I have not found the exact answer
why heavy water has a sweet taste perhaps due to the fact that heavy water
has a large molecular weight he small corrects with the receptors of sweet
taste causing such a reaction hopefully this video was interesting and useful
for you if you liked this video don’t forget to give it a thumbs up and also
support channel on patreon I’m also thankful to all of my patrons who have

  1. Do you want a t-shirt from this video? Check out our new store with unique design:

  2. Thoisoi…. holy cow, you look totally different than what I had pictured in my mind.
    Great video, nice experiments too.

  3. does D2O really exist in water? I would have expected HDO, as H2O also tends to fall apart and recombine, which can be observerd by the conductivity of pure H2O.
    So, why should the few Deuterium Isotopes specifically recombine with Deuterium? I can imagine that D2O is more stable then H2O (this is how Deuterium can be separated from Hydrogen), but the difference is small (which is why separating Deuterium from Hydrogen is so energy intensive)

  4. If you can't pronounce english words, write down your text and ask your girl friend to read.

  5. I'm thinking you might have compared the viscosity of the two substances better by placing both cups on an evenly vibrating surface, that should make the difference obvious. It's a bit hard to see this way.

  6. 10:30 "The bond" (using the harmonic oscellator, the force constant and further constants for anharmonic oscellators) between the atoms is roughly the same, it mostly depends on the electron structure and that doesn't change. The isotope masses change frequencies of rotation and oscillation modes, but the reactions shouldn't be affected by "the bond".
    Classically (as for example in my quantum mechanics lecture) the explaination of hydrogen/deuterium reaction changes goes as follows: the hydrogen, being the lightest atom in chemistry can tunnel through potential barriers and contributes to the rates significantly, deuterium is twice as heavy and the transmission coefficient of ingoing "particles" includes a term with e^(-m), the tunneling reaction is significantly hindered.

  7. Makes me wonder how deuterium fluoride would behave with the proton being somewhat less 'exposed'.
    Would the neutron 'shield' the eleftropositivity of the nucleus?

  8. 1:20 It's not D2O, it's mostly HDO, the semiheavy water:
    "In normal water, about 1 molecule in 3,200 is HDO (one hydrogen in 6,400 is in the form of D), and heavy water molecules (D
    2O) only occur in a proportion of about 1 molecule in 41 million (i.e. one in 6,400^2)" on Wikipedia

  9. Very interesting! I didn't know it was more difficult to reduce or boil! Though I sort of guessed it would be…

  10. Finally see the man behind all these awesome videos. I dig the Russian accent saying the names of compounds lol. Please find the time to make more videos in English. Great work.

  11. Using a pem electrolyser is a way better way to make d2 gas because when you use a metal like calcium you trap 66,66% of D2 on the Ca(OD)2. A better metal would be lithium in order to trap only one D atom in the Li(OD) instead of 2 in the Ca(OD)2 .

  12. I have seen a video from i ndia, they found there a ancient tank, over two thousand years old, full with a lot of deuterium this heavi water ,look like them vimanas engines has used this deuterium for flying !

  13. You really show stuff that you can’t find anywhere else on YouTube. Rare earth metal reactions, burning iridium, burning deuterium..
    Please never stop being awesome

  14. Isn't naturally occurring "heavy water" mostly HDO, with one atom each of protium and deuterium? So that D₂O is doubly rare (in nature)?


  15. I live 45 kms away from the biggest heavy water plant in the world. Nowadays, thanks to our neoliberal president is not running…

  16. I suspect that heavy water, in large quantities is poisonous/toxic. A lot of biological chemistry depends on hydrogen bonding, the reaction between a proton and local chemical moities. The moment you introduce a neutron into that binding system, stuff has got to happen, stuff that god did not intend to happen. A little taste, you are diluting the deuterium oxide in virtually an infinite amount of H20 molecules. Increase the volume of D2O, I'd be very nervous myself. Considering that two DNA strands are bound together via hydrogen bonds along the long axis of the DNA molecule, you don't want those strands either separating too easily, or not separating at all.

  17. "I do not advise anyone to drink heavy water. It's dangerous. But I can; I am a professional."
    Uh, being a professional isn't a shield against harm. The heavy water doesn't care one whit about that.
    BTW, you might want to tell us what those dangers are…


  18. Thank you ever so very much for making this video!!! 🙂
    I never knew that heavy water had a slightly sweet flavour.

  19. Deuterium is responsible for the spiral shape of the DNA molecule. The backbone of DNA is regular hydrogen and the D2 placed at intervals gives it a twist. Tritium messes this up and is responsible for destroying 50% of all life on the planet since 1960. This includes humans. See "fertility rate decline"

  20. Interesting …. work in a chemical lab doing research all of my life. And yes, despite safety rules I occasionally tasted my experiments (we all do it I suspect) when the risk is reasonably low.

  21. Very interesting, but I doubt, that Acetylene and KMnO4 form Oxalic acid, as oxalic acid is easily oxidized by KMnO4 solutions to CO2 and Water. We also use Oxalic acid as a titrametic standard at work to test for the concentration of KMnO4 solutions used for titrations, as they tend to loose some active substance over time forming MnO2. And the oxalic acid is oxidized in the reaction reducing the KMnO4, as you can observe by the solution going colorless 😉

  22. So.. the Hydrogen isotope with two neutrons, Tritium, weighs 3.0160492 atomic units.
    Helium 3, with one neutron and two protons, Helion, weighs 3.0160293 atomic units.
    I get that we can carefully react a bunch of hydrogen and deduce the atomic mass from molar quantities. That is fine.
    But how did Alvarez and Cornog know how to weigh Helion, to deduce it's atomic mass, in 1939?
    Helium doesn't react, so how can we know the atomic masses of its isotopes?
    It turns out (I read the paper, see link below for summary) that the way these folks were deducing the atomic mass was as follows:
    They purchased a sample of helium, and then created a magnetic field that they supposed would accelerate ions of a given charge and size, forming a current flow out of the gas chamber, through the magnetic field. Then they would measure the resulting current flow, in amperes, to know the concentration of those ions in the gas sample. So, first they set the magnetic field for the predominant isotope of Helium (4He), and noted the abundance of current induced by the field. Then they set the magnetic field for the smaller isotope, 3He, and measured it.
    I find the whole thing hugely spurious and contrived, but whatever.
    Chemistry is a fabled agreed upon.

  23. What effects on the body does heavy water have ?
    Great video Thoisol thanks for making them 👍🏻

  24. 13:40 “i do not advise anyone to drink heavy water, its dangerous. But i can drink it, i am a professional .”

  25. I see you have purchased the Deuterium Oxide from Bob Lazar.
    Are you gonna tell us about the element 115 next time?

  26. Drinking a few millilitres of heavy water isn't that dangerous. For starters, you already have a spoonful of the stuff in your body from the deuterium content in naturally-occurring hydrogen. Yes, if all the hydrogen atoms in your body were replaced with deuterium you'd probably die, but that would require all your water and food sources being fully deuterated for a month or so. (Put it this way, it's an extremely expensive way to poison someone.)

    Compare it this way: we don't consider ethanol toxic, but if a 70kg human drank 700g of ethanol (about two bottles of vodka) in one sitting, that would quite probably be deadly. So ethanol is fatally toxic at around a 1% concentration in the human body. By contrast, the heavy water fraction in the body would need to be about 30% to kill someone. So, ballpark figures, heavy water is at least an order of magnitude less toxic than pure ethanol, or put another way it's roughly as toxic as beer (which typically is 4% ethanol).

  27. I wonder what the thermal characteristics are vs normal water in say an open or closed loop water cooling system. I imagine if you filled a water cooling loop with pure heavy water you wouldn't need biocides to prevent algae formation? Since it's denser it should also have a higher thermal capacity?

  28. Now this is the voice I subscribed to. I just saw the new video with the new narrator and just… No. Sorry. I have to unsub because of that voice. I like your accent.

  29. The taste of plastic is becose the h2 feeds the plastic en the essens of the plastic goos back

  30. Interesting? Absolutely! A thorough introduction to a material I was aware of but, about which, I was lacking any real information. Useful? well… errr… I'm sure it will come in handy… sometime

  31. There is a song about that story with heavy water and nazzi, called Saboteurs by Sabaton. And very well detailed on sabaton history. Great video, btw. I'll recomand to others.

  32. I feel like we should clean up the gene pool and the way to decide who gets shocked away depends on their YouTube comments. Every video I watch has boring repetitive meme comments. But this video actually seems to have intelligent people underneath.

  33. So amazing content! Experiments! Comparisons! Properties… it actually inspires me to think of possible uses of it.

    But one think I need to point, pleease work a bit on your accent, or rather intonation. It is really difficult to focus.

    If I was native in english I would probably never dare to point it, but I am from Slavic nation as you are … and we simply need to sacrifice to master the language those guys are lucky to be born with. Even so, we should work not only in vocabulary or grammar, the intelligibility is also important (and I must admit, I needed to hold my phone and intently focus, in order to understand you through the intonation)

    Thank You for Your hard work and interesting program 🙂

  34. Oh great! This'll become the next "fad" in bottled water! I can't wait to see passion fruit infused heavy water at the convenience store….

  35. I work a lot with electrolysis. Two of the byproducts of electrolysis many people don't know exist are tritium and deuterium. I did not know this for a long time and never collected it. The volumes of tritium are so low that it is hard to detect. I finally managed to capture some a few years ago and make my own tritium glass tube. Being as it was not that much the two did not glow very bright. I did manage to prove that it is in there. I do not have my tritium glass rod anymore as I dropped it and broke it. They are fun elements that are more abundant than I ever thought they were!
