Question

Define kohlrausch law. give two applications.​

Answer 1

Answer:

(i) Calculation of molar conductance at infinite dilution for weak electrolytes. λm∞(CH3COOH)=λ∞CH3COO+λH+∞ (ii) Determination of degree of dissociation of weak electrolyte.

hopes it helps you.

Answer 2

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.

(i) Calculation of molar conductance at infinite dilution for weak electrolytes.λm∞(CH3COOH)=λ∞CH3COO+λH+∞

(ii) Determination of degree of dissociation of weak electrolyte. If at any concentration C the value of molar conductance is λme then.
