Plating Metals

I was thinking of plating iron or magnesium on to copper with a galvanic cell. Would this work?

3Cu(s) + 2Fe2+(aq) --> 3Cu2+(aq) + 2Fe(s)
Cu(s) + Mg2+(aq) --> Cu2+(aq) + Mg(s)

In the cathode, when the Cu turns in to Cu2+ and makes Cu(OH)2, of what use is it? And in the anode, when the O2- makes water with H+, of what use is the OH- that's left?

It wont work by itself, you need electroplating (with external source of current).

In general there is no use of byproducts.

Judging from the way you asked the question and from the drawing you should start with a general chemistry textbook to get a grasp of what it is all about, then go for some electroplating handbook for recipes.
