Variation of Conductivity and Molar Conductivity with concentration
CHXII03:ELECTROCHEMISTRY

330467 Molar conductance of KCl increases slowly with decrease in concentration because of

1 Increase in degree of ionisation
2 Increase in total number of current carrying species
3 Weakening of interionic attractions and increase in ionic mobilities
4 Increase in hydration of ions.
