What is the potential of a cell made up of zn/zn2+ and cu/cu2+ half-cells at 25ºc if [zn2+] = 0.25 m and [cu2+] = 0.15 m?

Cell potential = +1.09V

Explanation:

Given:

[Zn2+] = 0.25 M

[Cu2+]  = 0.15 M

In this electrochemical cell, Zn/Zn2+ half cell will serve as the anode and Cu/Cu2+ will act as the cathode.

The two half reactions and the reduction potentials based on the standard reduction potential chart are:

Anode (Oxidation):

.......E°(anode) = -0.76 V

Cathode(Reduction):

........E°(cathode)= +0.34 V

Overall reaction:

Based on the Nernst equation:
