As we learnt in 

Equilibrium Constant from Nernst Equation -

E_{cell}^{0}=\frac{2.303 RT}{nf}log K_{c}

K_{c}= equilibrium constant.

F = 96487 C mol-1

R= 8.314 JK-1 mol-1

To determine the resistace of a cell, its conductance is measured using KCl solution. The standard values of specific conductance of KCl solutions at different concentrations are known.

\therefore KCl\, \, is\, \, used
