Solution: Two voltaic cells are to be joined so that one will run the other as an electrolytic cell. In the first cell, one half-cell has Au foil in 1.00 M Au(NO3)3, and the other half-cell has a Cr bar in 1.00 M Cr(NO3)3. In the second cell, one half-cell has a Co bar in 1.00 M Co(NO  3)2, and the other half-cell has a Zn bar in 1.00 M Zn(NO3)2.(b) Calculate the total potential if the two cells are connected as voltaic cells in series.
