Question 1
How many moles of silver metal are produced in 1.2 hours by the electrolysis of AgNO
3(aq) using a current of 6.0 A?
Question 2
Many different ways have been proposed to make batteries. One cell is set up with copper and lead electrodes in contact with CuSO
4(aq) and Pb(NO
3)
2 (aq), respectively. If the Pb
2+ and Cu
2+ concentrations are each 1.0 M, what is the overall cell potential?
Pb2+ + 2e–→Pb | E° = –0.22 V |
Cu2+ + 2e–→ Cu | E° = +0.34 V |
