How does molar conductance of a weak electrolyte vary with its concentration in solution?

Answer

The molar conductivity of a weak electrolyte like CH3COOH and NH3 etc. increases with decreases in concentration of the solute in solution. The increase is vary rapid at lower concentrations. The increases in the molar conductance with dilution is due to an increase in the effective degree of ionisation (α) at lower concentration and release of more free ions in the solution.
