Consider two cells, the first with Al and Ag electrodes, and the second with Zn

Question

Consider two cells, the first with Al and Ag electrodes, and the second with Zn and Ni electrodes, each in appropriate 1.00 M solutions of their ions. If connected as voltaic cells in series, which two metals are plated, and what is the total potential If connected such that one cell acts as a battery to power the other as an electrolytic cell, which two metals are plated, and what is the total potentail If 3.70 g of metal is plated in the voltaic cell, how much metal is plated in the electrolytic cell

Explanation / Answer

Solution:

a) for voltaic series Ag and Ni,    E = 2.98 V

b) as a battery Ag and Zn,           E = 1.98V

c) 3.70g/107.868/2*65.38= 1.121g
