According to IUPAC convention, the standard electrode potential is defined as the standard reduction potential.

For the ${\text{Cu}}^{+2}/\text{Cu}$ electrode, the reduction half-reaction involves the gain of electrons by ${\text{Cu}}^{+2}$ ions to form solid $\text{Cu}$.

The reaction is ${\text{Cu}}^{+2}+2e^{-}\to \text{Cu}$, and its standard reduction potential is $+0.34\text{ V}$ with respect to the Standard Hydrogen Electrode (SHE).

Answer: ${\text{Cu}}^{+2}+2e^{-}\to \text{Cu}$
