Molar conductivity.

Text Solution

Verified by Experts

It is defined as a conductance of a volume of the solution containing ions from one mole of an electrolyte when placed between two parallel plate electrodes 1 cm apart and lf large area, sufficient to accommodate the whole solution between them, at constant temperature. It is denoted by `^^_(m)`.
