Question

Define molar conductance of a solution. State its unit. How is it related to the specific conductance of a solution?

Answer 1

Molar conductance : It is the conductance of all ions furnished by one mole of an electrolyte present in a definite volume of the solution.
Its unit is $oh{m}^{-1}c{m}^{2}mo{l}^{-1}$. Molar conductance ${\Lambda }_m$ is related to specific conductance $k$ by the following equation
${\Lambda }_m=\frac{k\times 1000}{M}$, where
$k$ is ${\Lambda }_{sp}$ and $M$ is molar concentration of the solution.
