I'm a bit confused by the electroplating of Zinc onto Copper, with Zinc (anode) and Copper (cathode) electrodes in a Zn(NO3)2 solution.
The reduction reaction is: Zn2+ + 2e- ---> Zn (s) (E_rxn = -0.76 V)
The oxidation reaction is: Zn(s) ---> Zn2+ + 2e- (E_rxn = 0.76 V)
Thus, in the overall reaction, all elements "cancel out" and E_cell = 0 V. Does this mean the reaction occurs spontaneously (although electrolysis is generally non-spontaneous)? Also, what is the overall cell reaction? I'm confused about this and can't seem to find any clarifying information online.
Thank you!
