State Kohlrausch's law and write mathematical expression of molar conductivity of the given solution at infinite dilution.

Text Solution

Verified by Experts

Statement of Kohlrausch's law : This states that at infinite dilution of the solution, each ion of an electrolyte migrates indepef!dently of its co-ions and contributes independently to the total molar conductivity of the electrolyte, irrespective of the nature of other ions present in the solution
This law of independent migration of ions is represented as
`^^_(0) = lambda_(+)^(0) + lambda_(-)^(0)`.
Where `^^_(0)` is the molar conductivity of the electrolyte at infinite dilution or zero concentration while `lambda_(+)^(0)` and `lambda_(-)^(0)` are the molar ionic conductivites of cation and anion respectively at infinte dilution.
