The standard reduction potential for the half-reaction Zn²⁺(aq) + ⁻2e → Zn(s) is -0.76 V; option A
The standard reduction potential of a chemical species is the a measure of the potential of a given chemical species to be reduced rather than being oxidized.
This measurement is done under standard conditions of concentration, pressure and temperature.
