Consider an electrochemical cell constructed from the following half cells, linked by an external circuit and by a KCl salt bridge.
- An Al(s) electrode in 1.0 M Al(NO3)3 solution
- A Pb(s) electrode in 1.0 M Pb(NO3)2 solution
a) Write the balanced overall cell reaction that will make the cell spontaneous. Keep in mind that aluminum will transfer 3 electrons per aluminum atom while lead will only transfer 2.
b) Calculate E cell
c) How many electrons will be transferred in the balanced overall reaction?
