I hope to clear any misunderstandings.
This video is one of the most coolest video i've seen about heavy water in whole youtube. You manage to show very vast difference of heavy water and regular non heavy water using fairly simple experiments.

My guess on why it would be sweet is that the body knows to ingnore the H2O in the mouth but the higher weight bypasses this and the body thinks it's a sugar alcohol (I.e Glycerol, Erythritol, Xylitol, etc) because of the OH groups.
Hahaha I never thought a chemistry channel would degenerate. OH groups? What OH groups? Unless you're talking about the 10^(negative something pretty big) hydronium (H3O+) + OH-.... Quantum level?... come-off it! That is such a throwaway answer. There is debate out there whether it tastes sweet or not.
You really show stuff that you can’t find anywhere else on UA-cam. Rare earth metal reactions, burning iridium, burning deuterium.. Please never stop being awesome
I tasted a few droplets of heavy water myself (I use D2O as a solvent for NMR-spectroscopy) and indeed: it is (very slightly) sweet. I would have liked to be able to taste more than a few droplets, but I don't think my boss would have been happy with this, as D2O is quite expensive: More than 100€ for a bottle of 100 grams......
@@FedeG86 It is so expensive because it is quite difficult to extract it from ordinary water (ordinary water contains 0.0156% heavy water). But I think Thoisoi2 has had more expensive chemicals in his videos. A lot of elements/metals cost a lot more than 100€ for 100 grams. In my lab we synthesize, but also buy all kinds of deuterated chemicals. These are most of the time much more expensive than heavy water. 1000-2500€ for 1 gram of one of these chemicals is not uncommon...
@@jimmorgan6213 I would say that the sweetness of heavy water is comparable to a ~1% sugar solution (~1 gram of sugar in 100 ml of water). The first time I tasted it, I was a bit sceptical beforehand and was quite surprised when it indeed tasted sweet. I am really quite curious why this is.....
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!
I should have added this to begin with but the reason tritium and deuterium are left after electrolysis is because you cannot electrolyze either of them. Another words I'm not actually creating tritium and deuterium inside the unit but merely they are left over from the oxygen and hydrogen production from water.
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.
I appreciate your hard work in doing all these experiments in all videos and also purchasing these Elements... Its risky but you do this for our Enjoyment... Love you man ! 😍😍🍻 Go on ! 😍
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
Perhaps a heavy water fermentation and then distillation to arrive at a Deuterium Vodka. If old paper can be used in the supposedly best vodkas then who knows? Just a thought. 🍸🍹⚡
Great video. I remember reading that in the early day of nuclear research the first sample of heavy water was fed to a mouse because the scientists were concerned that Deuterium Oxid would be a dangerous chemical poison. I have no invormation or if or how the D2O was extracted from the mouse. This was an enlightening chemistry experiment. Especially how the mass of the atoms can affect the chemical reactions. Another excellent video! Thanks.

The difference in taste between ordinary and heavy water can be explained by different vibrations of the molecule, as explained by biophysicist Luca Turin
The thing that interesting me even more about tritium, is super heavy water made of tritium (T2O) but i doubt he would have anytime access to it, or at least not to amounts of it to play with it.
Well yeah I tought of this and I knew that he probably cannot get that much tritium but actually I have a very VERY tiny ammount of tritium in a glowstick and the tritium inside glows for ten years. Anyways it was worth a try.

@@Blido I know and I wanted a video about pure tritium not super heavy water but I knew he probably can't get his hands on reasonable ammounts of tritium.
I do like the idea that if you can use unenriched uranium that once you get one plant set up you can draw a little power off it to make heavy water for subsequent ones or at least for its own supply
So if heavy water is D2O, and regular water is H2O... Does DHO exist? (water made from one Oxygen, one Deuterium, and one regular Hydrogen)? It would seem pretty weird to me if it didn't.
Thoisoi2: Hopefully, this video was useful and interesting for you. Me: Are you kidding me? I've never seen / heard of any chemistry professor drinking heavy water! Of course it's very interesting!

Hydrogen doesn’t burn, it fusions when it comes in contact with heat. The hydrogen sucks in the heat and capsules it inside itself, not the other way around. A burning gas is a gas that the flame uses as fuel, it consumes the gas til there is no more. Hydrogen atoms consumes heat that is damaging to us til there is no more intense heat left. If there is no dmg left then the hydrogen would stop make that chemical reaction and rise as normal towards the sky. A fusion is something like a reversed bomb, a heat protection don’t confuse it with fuel for heat. Fusion don’t need oxygen to make the chemical reaction while burning oil as an example requires oxygen to burn.
Wonderful demonstration. Thank you. Has anyone tried to grow food with heavy water and eventually see the effect of heavy water replacing regular hydrogen with deuterium within the human body? Does it effect enzyme action or protein 'shape'?
I think heavy water messes with your bodies chemistry because it behaves differently. For small amounts it's fine but if you started to drink the stuff regularly it would not be healthy at all
deuterated water does not behave in quite the same way in a living organism. Your body can tolerate small amounts just fine but in larger quantities, where it becomes a significant proportion of your fluid intake, it interferes with cellular metabolism. When that happens a variety of unusual symptoms occur that are similar to chemotherapy.
Makes me wonder how deuterium fluoride would behave with the proton being somewhat less 'exposed'. Would the neutron 'shield' the eleftropositivity of the nucleus?
Apparently, heavy water is relatively safe to drink, so long as it does not exceed about 10% of the total water mass in your body. Of course, it is largely pointless to drink it - except to sample the possibly sweet taste - when it is so expensive to buy.
