Answer 2

Answer:

Nernst gave a relationship between electrode potential and concentration of electrolyte solution known as Nernst equation. For a general electrode reaction,

Mn+(aq) + ne- → M(s)

the Nernst equation is

E(Mn+∣∣∣M) = E°(Mn+∣∣∣M) − RTnFln[M(s)][Mn+(aq)]

Where E(Mn+|M) = electrode potential

Eo(Mn+|M) = Standard electrode potential

R = Gas constant, T = Temperature, F = Faraday constant

n = Number of electrons gained during electrode reaction

[Mn+(aq)] = Molar concentration of ions, [M(s)] = concentration of metal

Significance of Nernst equation:

1) It can be used for calculation of cell potential

2) It can be used for calculation of concentration of a solution of Half cell.

3) Equilibrium constant can be calculated from this equation.
