for a galvanic cell
E0cell = E0(right) -E0(left)
when SHE is used, E0(left) = 0.00V
then
-0.311 V = E0(right) - 0.00 V
thus E0(right)= -0.311 V
this is the standard electrode potential of right half
cell.Now
use this value to get cell potential when SCE is connected
When SCE used, it has an electrode potential value= 0.241 V
then
E0Cell =E0(right) -E0(left)
=-0.311 V-0.241 V = -0.552 V
thus
cell potential = -0.552 V

Standard potentials are measured against the standard hydrogen electrode (SHE). Because it is not always convenient to use a S.Н.Е., often other reference electrodes are used. The saturated calomel electrode (SCE.) is one commonly used reference electrode, with a reduction potential of +0.242 V versus the S.H.E. Using a table of standard reductions, determine what the standard reduction potential of each reduction half-reaction would be versus the S.C.E Cl2 (g) + 2e-→ 2 Cl-(aq) E1.36 Fe3 + (aq) + 3...
