my lil bro asked me for help on his chem, and well you know chem in highschool was too long ago =p
anyone know the chemical equation for the reaction that occurs when you remove zinc layer from iron with HCL?
thanks in advance

Word equation
Zinc + Hydrochloric acid ---> Zinc Chloride + Hydrogen
Symbol equation
Zn(s) + 2HCl(aq) ---> ZnCl2(aq) + H2(g)
The hydrogen effervesces away and the zinc chloride dissolves leaving bare iron.
Alternatively you could also anodise the zinc coated iron in an electrolytic cell
Ionic equation - at the anode
Zn(s) ---> Zn2+(aq) + 2e-
The zinc ions go into solution leaving bare iron
You're welcome

Zn + 2HCl ----> ZnCl2 + H2
But it will also react with the iron...
