Hydrogen Answered

hello I'm a new user would anyone like an instructable on how to produce hydrogen in your own home?

oh ok only electrolysis ? Ive got a nice and quick chemical reaction that makes liters (or lots at least) of it now to head off to the store

Search Hydrogen in the search bar, there is 15 instructables on how. Enjoy. :)

Didn't know there was an inexpensive (!) way to produce large quantities of hydrogen via chemical reaction, but I'd love to see it!

(Hydrochloric acid is often sold as patio or concrete cleaner - check the hazard warnings on the bottle)

Or, Sodium Hydroxide + Zinc. (It's a "clean" reaction that doesn't leave behind nasty, toxic gunk).

Where does one find cheap zinc in decent quantities? Aluminum is everywhere, but the only place that pure zinc is used that I know of is casings on carbon-zinc batteries.

At your local hardware store, they're likely to have two different kinds of bolts and screws. One kind will be gritty, lump-ily coated, and gray. The others will be either aluminized, electro-galvanized, or just solid steel. (They'll be shiny). The coating on the gray kind is zinc, and it's just a simple matter of scraping it off. Basically, anything that's been "hot-dip" galvanized has been soaked in zinc. I'm certain there are methods of producing zinc, but they've slipped away at the moment.

Sodium Hydroxide + aluminum

well, not exactly inexpensive as it takes a great deal of energy to make AL from bauxite.... but if you want to do a cheap (dollar wise) experiment...... Just be careful, the reaction is energetic and makes a great deal of heat. Not to mention the dangers of the liquids involved ;)

Absolutely. Aluminum foil is one of the only readily-available sources for pure aluminum.

Go for it! It's probably been done before, but your contribution is always useful. Remember, take good photographs, use the macro function on your camera, and document it well. If you're going to make an Instructable, make a good one.

macro function? never heard of that, what is it? do all cameras have it?

btw, it should be noted that my camera is an old Kodak (by old I mean 1999/2000)

right more chemistry then im pretty sure the easist way would be to react magneisum with hydrochloric acid or similar this is what we use at school and im guessing it is pretty cheap as it is used everyday

Magnesium is difficult to get compared to aluminum, and hydrochloric acid is no easier to get than sodium hydroxide is.

well that just an english version we can get hold of both reltivly easy

It has, but a new, modified, or just plain different one would be nice. I never can make it work, maybe your system will work better for me.
