Question

The standard reduction potentials of Cu2+|Cu and Cu2+|Cu+ are 0.337 V and 0.153 V, respectively. The standard electrode potential of Cu+|Cu half-cell is

Options

A.0.184 V
B.0.827 V
C.0.521 V
D.0.490 V

Solution

$E_{Cu^{+}|Cu} = \frac{2 \times E_{Cu^{2 +}|Cu} - 1 \times E_{Cu^{2 +}|Cu}}{2 - 1} = 0.521\text{ V}$
