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.

$straight k equals space 1 over straight R open parentheses 1 over straight a close parentheses$

The quantity 1/2 is cell constant.

L --> Distance between 2 electrodes

a --> Area of cross section

R --> Resistance
$Also comma space conductivity comma space straight k equals space fraction numerator Molar space conductivity over denominator Volume space of space solution end fraction thus comma space molar space conductivity space equals space kV$
