Question

What is meant by ‘limiting molar conductivity’?

Answer 1

Answer:

Limiting Molar conductivity is the conductivity of the solution at infinite dilution, i.e. all the ions have dissociated or the ions are farther apart. Conductivity of electrolyte decreases with decrease in concentration as number of ions per unit cm of surface area decreases upon dilution.

Answer 2

Answer:

The limiting molar conductivity is defined as molar conductivity of the solution at infinite dilution. Hence we can say that the conductivity of an electrolyte at approximately at zero concentration is called limiting molar conductivity. Value of limiting molar conductivity is always less than unity.
