How to create hydrogen gas/storing?

[StrapOnFetus]

Tell me if this is sound logic. So if I pretty much wanted to create hydrogen gas to experiment with. I would need a battery setup running a conduit of negative and both positive. With two stainless steel or maybe platinum "electrodes".The electrodes will be both placed into water with either salt or acid. The hydrogen gas will be generated by the cathode. (negatively charged electrode) What are the conditions I would have too have available to store hydrogen gas?

I can picture something like, very large test tubes hung upside down with 2 electrodes in place. This would be on the bottom with a workable drainage/airtight cork of some kind. Very slowly I could release the eletrolytic water while the hydrogen will stay on top. I would have in the positive test tube, oxygen while the negative will contain hydrogen?

Okay. There are many ways to make hydrogen: zinc(?) and copper plates, electrically charged in water; pyrolysis of wood or coaldust... (650-900 degrees, very little O2).
I'm not familiar with storage methods, but a pump would seem in order (no sparking please).
Don't they have this on wiki?
Check out carbonite based "town gas"... I just checked wiki and they call it a primitive explosive... they don't get around to mentioning it's use in lighting the way and keeping warm.
I'm too tired to make sense now, but I hope something up there helps.

Thank's man, will do. Figuring out how to store hydrogen gas is annoying. And probably gonna be time consuming.

You can produce hydrogen gas by placing zinc in hydrocholic acid.

Though, obviously. I don't think I need to mention the dangers of hydrochloric acid OP.

Make sure to use goggles and gloves if you use this approach.

Pretty sure he's right. Though the water thing is probably safer, but the reaction's slow and the producing lead will corrode if the water isn't denatured enough.

Anyway, you're asking the secret of the century. Even on Top Gear (UK), they say the holy grail of the car is how to store hydrogen on a commercial level (for use in fuel cell, plastic ion stripping thing)

Good luck!

Good luck!

Thanks guy's

The ONLY way I can see it done, is in a glass ampule or in some kind of air tight balloon.

Don't worry I will be safe. Goggles and no smoking :D Although I do recollect a friend who burn his thumb with hydrochloric acid.

don't forget to add a very small amount of salt since water is not a good conductor. table salt will do.

you don't want to add too much salt either because chlorine gas will be produced, instead of oxygen, which is of course, toxic.

You cannot break down salt while it's in water.

Only molten salt (700 Celsius) can be broken down into sodium and chlorine.

It is actually practical to extract hydrogen (and oxygen) directly from sea water.

you can, and it is called electrolysis of brine, given by the equation NaCl+H20=>NaOH+H2.

NaCl+H20=>NaOH+H2+Cl2. with the chlorine gas appearing in the positive electrode. (not balanaced of course) and i never said you cannot extract H2 from salt water have i?

I know hydrogen gas is easy to make. Hydrochloric acid and zinc, or electrolysis of salt/acid based water. The real question I need answered by you fine gentlemen. Is how does one store hydrogen gas, I need a crude, "but" safe way. I don't want to be making loud booms on my garage workbench. :D

First person to come up with a crude but viable method, get's 10+ chemist cool points :D

On a side note, I recall a friend of mine trying to synthesize small amounts of Nitroglycerin. Well he did not store it properly, and while he was at work. A mouse or critter of some kind knocked the ampule over. His 8k work bench with materials was destroyed with a boom that freaked out the neighbors. Needless to say he came home with police waiting for him, wanting to question what was going on. lol

Also, you are all extremely intelligent people. GOOD LUCK! BE SAFE!

Guess I answered my own question. Look at this guy, quite novel really.

Oh, like that one movie with Gerald Butler?

I'll look it up and come back to you with a report on the subject.
