Collecting Hydrogen and Oxygen

Step 6: Extra Possibilities

Along with making Hydrogen and Oxygen there are other things you can do with this concept. One is Making Oxide salts (i.e. metal+Oxygen such as Fe2O3) although this will not allow you to collect gaseous Oxygen, you can make pigments out of this such as turquoise blue with Copper or Orange with Iron. You can also make Aluminum powder for thermite, with the positive being Aluminum and the negative being Carbon (Graphite/pencil lead) the Aluminum either does not bond or it decomposes. If I'm wrong it will stay bonded but can still be used as a pyrotechnic. You may also plate a metal using this with the plating metal on the positive and the object to be plated on the negative although this will also crate it's oxide. All you have to remember is that the positive will dissolve into an oxide salt and the negative will be plated. Have fun experimenting

you can also get Cu(OH)2 by using a copper electrode. When you have enough Copper Hydroxide heat it up until it turns a black color.
the reaction looks like this:
Cu(OH)2 ---> CuO + H2O
you can use the CuO in thermite inplace of the Al2O3 it might explode

Hello, I tried what you described step by step, what happened is that the ( - ) negative side bubbled yes but the ( + ) positive side didn't give out a single tiny buble !! , after i collected much enough of the gas, i burned it to make sure it is not hydrogen and it wasn't indeed. becasue as u said the hydrogen bubles from the positive side. So what you think is wrong here? and why isn't the positive wire giving gas ?

How many volts did you input sometimes people dont have enough electricity

dude i tried to make aluminum powder but i got Al(OH)3. Also i want to make Fe2O3. i put 2 nails for electrodes. at start the water is brown but after it turns green-blue. is it clorine, copper oxide or what? plz help me out.
