Question

Assertion: Molar conductivity of a weak electrolyte at infinite dilution cannot be determined experimentally.
Reason: Kohlrausch's law helps to find the molar conductivity of a weak electrolyte
infinite dilution.​

Answer 1

Answer:

assertion is true buut reason is false

Answer 2

Answer:

The molar conductivity of weak electrolytes at infinite dilution cannot be

determined experimentally, firstly because the conductance of such a solution is

low and secondly because dissociation of such an electrolytes is not completed

even at high dilutions.

The molar conductivity of such an electrolyte at infinite dilution can be

calculated using Kohlrausch’s law.

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.

Hence,Both Assertion and reason are
