Why does the iron plate becomes brown?
I have no precise idea, but I think it might be related to the loss of electrons of the iron plate. Could someone help, please?

My idea was so stupid. I am almost sure that it is because the iron is going into solution and the copper is coming out of solution forming the brown thing in the iron plate. Am i right now?
