Practising with hcl will give off H2 but you still will have tiny amount of hcl gas that evaporates. It's soluble in water and will be neutralized by Aluminium foils.MarcoP said:Romix said:Would this technic work?

I saw something similar in Hoke's book and there is not reason why it wouldn't work, but I reckon its better if you use acid peroxide. Did you mean Nitric instead of HCl fumes? HCl doesn't generate NOx.
Yes that's what I meant. It's only a theory, not tried it yet.MarcoP said:Oh, you meant Al foils for HCl fumes and Cu foils for Nitric's. Sorry about that, I'll sit back and follow the thread :roll:
Al can also be used for nitrics, and it's cheaper. But I think it's just a waste of nitrate ions. I chosen Copper because of its place in Reactivity Series and I wona go through it.MarcoP said:Oh, you meant Al foils for HCl fumes and Cu foils for Nitric's.
