Solution: A Cu-Zn voltaic cell based on the reaction in the equation given below. Zn( s ) + Cu2 + ( aq )  →  Zn2 + ( aq ) + Cu( s )Which metal is oxidized in this voltaic cell?

Problem

A photograph shows a voltmeter attached to a Zn electrode in a 1 molar ZnSO4 solution, and a Cu electrode in a 1 molar CuSO4 solution. The two solutions are in contact with each other through a porous glass disc.
A Cu-Zn voltaic cell based on the reaction in the equation given below.
Zn( s ) + Cu2 + ( aq )  →  Zn2 + ( aq ) + Cu( s )

Which metal is oxidized in this voltaic cell?
