Question

what you mean by kohlrausch law and its applications

Answer 1

Hiii machiii ✋...

➡️ Kohlrausch's law states that the equivalent conductivity of an electrolyte at infinite dilution is equal to the sum of the conductances of the anions and cations. If a salt is dissolved in water, the conductivity of the solution is the sum of the conductances of the anions and cations.



➡️ the finite dilution, when dissociation of electrolyte is complete then every ion makes a definite contribution in the molar conductivity independent of the other ions present along with it in the solution.

➡️ Determination of for weak electrolytes : The molar conductivity of a weak electrolyte at infinite dilution cannot be determined by extrapolation method. However, values for weak electrolytes can be determined by using the Kohlrausch's equation.

Answer 2

Kohlrausch's law is a statement in physical chemistry: the migration of an ion at infinite dilution is dependent on the nature of the solvent and on the potential gradient but not on the other ions present.
