Chapter 17, Problem 35QAP

Suppose $E_{\text{red}}^{°}$ for ${\text{Ag}}^{+}\to \text{Ag}$ were set equal to zero instead of that of ${\text{H}}^{+}\to {\text{H}}_2$ . What would be
(a) $E_{\text{red}}^{°}$ for ${\text{H}}^{+}\to {\text{H}}_2$ ?
(b) $E_{\text{ox}}^{°}$ for $\text{Ca}\to {\text{Ca}}^{2+}$ ?
(c) E° for the cell in 33(c)? Compare your answer with that obtained in 33(c).
