Ionic conductances
Ionic conductance:
The conductance of an electrolytic solution depends upon the conductances of the ions forming the electrolyte. We know that the molar (or. equivalent) conductance of an electrolyte solution increase with dilution and at infinite dilution it approaches a maximum limiting value.
At infinite dilution, an electrolyte dissociates completely into ions and each ion contributes it's definite share to the total molar (or, equivalent) conductance of the electrolyte. In other words l, the molar (or, equivalent) conductance of an electrolyte solution is an additive property, I.e., the sum of the conductances of the ions (called the molar (or, equivalent) ionic conductances) in the solution.
