anyone know where to get a lot of HCl and Zinc?
or if you know a better way let me know. thanks

ummm i pretty shure you can find it on ebay ....i look in to it though

if you mix water and an element called boron together you get hydrogen

sodium hydroxide and aluminum

or hydrochliric acid and aluminum....or any oxidation/reduction which releases instead of using it's hydrogen....there are probably a few thousand.....most of which boiling down to a few simpler equations....

Hydrochloric acid is easily found under its antiquated name, "muriatic acid." For some godawful reason it's usually stocked with the paint thinners and supplies at hardware and home supply stores such as Home Depot and Lowes... Though it's generally used for cleaning masonry.

You probably have some zinc in your pocket right now. All US pennies made after 1982 are primarily zinc, quite pure, with a coating of copper plated on top that's a handful of atoms thick. A quick kiss with a grinding wheel will expose enough zinc to let the acid in; The hydrochloric acid will attack the zinc but not the copper, leaving you with zinc chloride, hydrogen gas, and the hollowed out copper husks of pennies.

Another good source for zinc is "die cast" metal toys (like Hotwheels knockoffs) which are commonly made of zinc or at least mostly zinc because the stuff is easy to melt and cast, and doesn't kill you quite as bad as lead.

If you want to make hydrogen, there are lots of ways. you could react acids with metals as others have mentioned, or you could do simple electrolosys using some 9v and carbon rods from pencils in a cup of water with some salt for conductablity (or you use metal but you would get other products) another is lithium from batteries in a quantity of water (but this is a more expensive way)
