`E^@` of zinc electrode is `-0.762V`. Calculate the single electrode potential of Zn electrode in decimolar `ZnSO_4` solution.

Explanation

Simplified Nernst equation for single electrode potential
`E = E^@ + (0.059)/(n) log C " (or) " E = E^@ + (0.059)/(2) log [Zn^(2+)]`
Substituting the values in the expression for the single electrode potential of Zn.
`E = -0.762 + 0.0295 log 10^(-1) = -0.7915 V`.
