Elemental Extractions #1: Hydrogen

[@dolotonightshorts]

so glad your making videos again

[@redoxalchemist9754]

So glad you're back! I'm also glad you've decided to make this specific series as well!

[@glenwoofit]

Great start to the series! I'm looking forward to seeing more.

[@jonhoyles714]

great vid as always, its so nice to have u back in the chemistry community again look forward to what u have planned next :)

[@mrhomescientist]

+jon hoyles Thank you very much!

[@ReDefighter]

This is great! Can't wait to see more videos on the rest of the elements! =) You rock!

[@S3v3n13tt3r5]

Great stuff, cant wait for more.

[@MrCrusader123]

Great video, this brings back memories from chemisty class in school. I'm looking forward to this series

[@sorsorscience0787]

I did electrolysis before but i put a 9-volt battery in sodium chloride solution bad idea (sodium hydroxide and chlorine made my protium impure). Ive also used it to make iron oxide, graphene, etc. Great video as always

[@lynx882]

This was very informative. You have a well developed skill for teaching others; at least in comparison to other KZbin content creators.

[@mrhomescientist]

+lynx882 Thank you very much! I always worry that I talk too much in my videos. There's just so much information I want to share though!

[@artosvanstel]

+mrhomescientist The amount of information you shared was exactly right, everything you said was interesting and informative without getting boring. I'd love to see more of this series.

[@mrhomescientist]

+Artos van stel Hey thanks a lot, I really appreciate that. :)

[@Electroblud]

The "Official" gas test for Hydrogen as I have been taught back in school is holding the inverted test tube to a Bunsen burner to make it "pop". That being said, I don't really see why you couldn't do that with a lit splint. You should be careful when doing this test with an upright test tube, though. If you're unlucky, the test tube might shatter because of the hydrogen/oxygen mixing (the probability of that is quite low, but our teacher always warned us about that).

[@ThePeterDislikeShow]

Also oxygen is much more soluble than hydrogen in water, so that could account for some of the lower than expected amount of oxygen.

[@DanaWebb2017]

I used zinc and sulfuric acid once and collected it in a plastic bag, touched it off with a match and it went off like a firecracker.

[@im0b]

great video

[@somefool6409]

Technically the first element is neutronium, but that's probably not going to be easy to make at home.

[@MuzikBike]

lol

[@codybostintorocks]

I loved it

[@alliasapettypancake9475]

when i first learned about electrolysis in school, i got inspired to do an experiment of my own, it was for the sake of exploring thou, all i did was make a mini electrolysis using graphite electrodes from a pensil connected to a 1.5 v battery and the electrolyte is salt water. i didnt know that high salt conc in the water make it to produce chlorine gas so all i got was a white deposit and green gas accumulating

[@mrhomescientist]

+Alliasa PettyPanCake That's what science is all about; experimentation!

[@alliasapettypancake9475]

mrhomescientist yeah and it was pretty fun! i look forward for your next vid :) tq for replying

[@aletoledo1]

I would have expected a bigger pop at the end with an entire testtube full of hydrogen.

[@aepceo1]

+aletoledo1 The "pop" comes from a reaction between oxygen and hydrogen which forms water. Since it was pure hydrogen, there was no oxygen. The oxygen is only added from the air once it's pulled out and since oxygen is heavier than hydrogen, not much makes it into the tube. Had he mixed the hydrogen and oxygen in a 2:1 ratio, it's entirely possible that the test tube would have fractured.

[@mrhomescientist]

+Justin Dixon Correct! If you collect both gases from the electrolysis together in one vessel, you have hydrogen and oxygen together in the perfect stoichiometric ratio and they explode very violently when ignited (don't try that at home!). Pure hydrogen has nothing to react with, so it only really burns at the opening of the test tube.

[@tommyzhao6600]

how do you ampuole hydrogen? it will burn

[@ThePeterDislikeShow]

How did your hydrogen container not float? The container doesn't look very heavy.

[@xAlphaSonicx]

This was a very enjoyable video! :D However, I would like to ask of you something: Do you think you could type up a procedure for you lab? So, for example, you could have a downloadable pdf that follows the steps in your video. That way, if someone tries to recreate this experiment, they have both written instructions and an example video to guide them. Just some food for thought. I'm excited for the next one!

[@mrhomescientist]

+Senmortaj That's definitely a good idea, and I have done something similar for some of my videos. They're linked in the descriptions of the videos that have writeups, or you can visit my blog directly via the link on the "about" section on my main channel page. My long term goal is to have a writeup for every video, but it takes a while to write those so it going rather slowly :) Thanks!

[@xAlphaSonicx]

mrhomescientist Ah, yeah, I would imagine so. I know how much I dreaded doing write-ups in my AP Chemistry class. lol Thanks for replying so quickly, and I wish you luck in that endeavor of yours! xD

[@chemicalmaster3267]

+mrhomescientist What do you think about doing a video on how to make potassium ferrioxalate trihydrate, a light-sensitive complex compound that forms very beautiful lime-green crystals? I think it would be great!

[@Jambivids]

Neat video

[@nikoskaravitakis9437]

you can make deuterium by throwing a small piece of lithium in heavy water li+d2o=liod+d2 or sodium but lithium is the least violent

[@damonjackson5857]

nikos karavitakis I actually never thought of that, lol

[@KylesYTU]

how would you seal an ampoule filled with flammable elements?

[@mrhomescientist]

+KmanMeteorProductions As long as the flame is far enough away from the sample it shouldn't be a problem. You can also seal things under inert gas to prevent ignition. I'm not sure how they make hydrogen ampoules, though, since it's a gas. Probably a sealed system that they fill with hydrogen and flame seal with no contact with the gas within.

[@KylesYTU]

+mrhomescientist thank you

[@juggernautonfire]

How would one go about ampouling hydrogen gas without it combusting? I'm assuming working under an inert atmosphere and using an oxyhydrogen torch?

[@tonytoi8556]

If it's pure hydrogen, it won't combust because there are no oxygen to activate thé reaction.

[@grejuli97]

pls do oxygen!! what can it be used for? is it bad for you in large amounts? etc

[@TheAmmoniacal]

Ions do not move from one electrode to the other, why does this misconception persist? Otherwise an okay video.

[@ElGatoLoco698]

I thought deuterium is heavy water, oxygen included. It's not?

[@Raykkie]

+ElGatoLoco698 Deuterium is an isotope of Hydrogen, instead of 1 protons it's made up of 1 proton and 1 neutron. Heavy water is normal water but with Deuterium instead of Hydrogen.

[@robmckennie4203]

anyone know what kind of potential gradient you need to ionize water?

[@FutureAIDev2015]

I've seen tutorials that use a 12v car battery.

[@sorsorscience0787]

instead of sulfuric acid would sodium hydroxide work? Or magnesium sulfate?

[@mrhomescientist]

+Sor Sor Science07 Hydroxide would probably work, but I think it isn't used much because of possible formation of solid hydroxides during electrolysis. I do list epsom salt in the video already, although I've heard that one can also form hydroxides after a while. Dilute acids or other salts are probably a better bet.

[@sorsorscience0787]

mrhomescientist So maybe a dilute form of hydrochloric acid?

[@DragonTigerKnight]

Ooo I se u are lighting my fire to make me pop! Because I the hydrogen bomb

[@devvrath123]

Sodium Hydroxide, aluminium and water should also produce hydrogen gas right?

[@mrhomescientist]

Good call! There are quite a few ways to make it and that's a good one.

[@devvrath123]

@@mrhomescientist Oh. I'm just working on a good way to collect it. I'm trying to store it in balloons.

[@mrhomescientist]

@@devvrath123 Depending on your end use, you might want to lead the gas through a drying tube to remove water and any tiny droplets from the bubbling solution.

[@devvrath123]

@@mrhomescientist Thanks for the advice.

[@sorsorscience0787]

wait so would hydrochloric acid work as a electrolyte

[@mrhomescientist]

It would, yes, but then you run the risk of chlorine or HCl gas contamination in your product.

[@sorsorscience0787]

+mrhomescientist oh

[@drphu]

OR you could keep the H container upside down to keep it in! AH tritium they once used that to light up watch hands!

[@aletoledo1]

I thought the watch hands were radium

[@seigeengine]

+DrPhu They DO use tritium to light up watch hands. If you mean the light up watches of the distant past, those used radium.

[@drphu]

Still radiation particles hitting florescent material right? radium was more dangerous?

[@seigeengine]

DrPhu Yes, tritium is essentially completely safe unless you consume it, radium was kinda safe but still caused lots of problems, and has since degraded because the radiation breaks down the phosphor over time.

[@mrhomescientist]

+DrPhu Surprisingly, that would still leak out over time. No matter how large the difference in densities between two gases, they will eventually diffuse into each other and the hydrogen would very slowly leak out anyway. I once had a fish tank full of sulfur hexafluoride (about 6x heavier than air) covered with a piece of lexan, but after only a few hours most of it had diffused out of the tank! It's a surprisingly relentless process.

[@finisher3012]

+mrhomescientist do you have a patreon page?

[@mrhomescientist]

+Nihar Rane No. I don't plan on getting one, either. The great comments and feedback are reward enough. Thanks for your support!
