What do you understand by molar conductivity at infinite dilution?

What is molar conductivity at infinite dilution?

Answer 1

1. The limiting value of molar conductivity when concentration approaches zero or dilution is infinite is called limiting molar conductivity `(Lambda_m^0)` or molar conductivity at infinite dilution `(Lambda_m^infty)`. It is represented either as `Lambda_m^0` or as `Lambda_m^infty`.
2. The molar conductivity at infinite dilution of an electrolyte is equal to the sum of molar conductances of its cations and anions, with each conductance term multiplied by the number of respective ions present in the formula unit of the electrolyte.
