Define limiting molar conductivity. Why conductivity of an electrolyte solution decreases with decrease in concentration ? |
| Answer» SOLUTION :The MOLAR conductivity of a solution at infinite dilution, i.e., when concentration approaches zero is called limiting molar conductivity. With decrease in concentration, i.e., with dilution, number of IONS per `cm^(3)` decreases DUE to large increase in VOLUME of the solution. as conductivity is the conductance per `cm^(3)` of the solution, hence it decreases. | |
