• Question

Express the relation among cell constant, the resistance of the solution in the cell and conductivity of the solution. How is molar conductivity of a solution related to its conductivity?

Solution

The conductivity (k) of the solution in a cell is the reciprocal of its resistivity.

The quantity  1/2  is cell constant.

L --> Distance between 2 electrodes

a --> Area of cross section

R -->  Resistance
