Chemistry

Many different ways have been proposed to make batteries. Onecell is set up with copper and lead electrodes in contact withCuSO4(aq) and Pb(NO3)2 (aq), respectively. If the Pb2+ and Cu2+concentrations are each 1.0 M, what is the overall cellpotential?

Pb2+ + 2e- ---> Pb E = -0.22 V

Cu2+ + 2e- ----> Cu E = +0.34V
