Aluminium Foil and copper

The reaction of copper chloride with aluminium strips the oxide layer and releases hydrogen. Taken from Newcastle University's Holmes' lectures 2007

And now you all have lung cancer.

even alluminium powder haves an oxide layer.

@PETN exactly correct

@GingleGangle1: the Hydrogen is liberated from the reaction of hcl and al.

[GingleGangle1]

Hydrogen?? I thought it was HCl.

cool flame

ive been thinking of this... a friend of mine told me that if i put aluminium foil in a can and heat ALOT with just a small hole for air, the al foil will lose its layer.. but if.. i take hcl or lye on al foil, it destroys this layer.. so before it eats all the pure aluminium.. cant i just add water to make it stop eating the aluminium and then powder to get some aluminium powder? (:

This would produce a controlled amount of Hydrogen gas because some of the Hydrogen will react with the copper in solution. I assume this is the reason for putting the copper in. You would have difficulty making the glass shatter because you getting a slow generation of the gas. Hydrogen is very light and escapes any open container very rapidly. I've made hydrogen candles from Zn/HCl mixtures and they'll burn for a long time.

IT is probably similar to the Sodium hydroxide(lye) and Alu foil demonstration that produces hydrogen.
