Kohlrausch` s law states that at :

Options

A. infinite dilution, each ion makes denitie contribution to equivalent conductance of an electrolyte, whatever be the nature of the ion of the electrolyte
B. finite dilution, each ion makes definite contribution to equivalent conductance of an electrolyte, whatever be the nature of the other ion of the electrolyte
C. infinite dilution each ion makes denite contribution to equivalent conductance of an electrolyte depending on the nature of the other ion of the electrolyte
D. infinite dilution, each ion makes definite contribution to conductance of an electrolyte whatever be the nature of the other ion of the electrolyte

Answer

A

Explanation

Kohlrausch law of indepdent migration of ions states that limiting equivalent conductivity (i.e., equivalent conductivity at infinite dilution) of an electrolyte can be represented at the sum of the indicidual contributions of the anion and cation of the electrolyte:
`Lambda_(eq.)^(oo) = Lambda_(+)^(oo)+Lambda_(_)^(oo)`
where `Lambda_(+)^(oo) =` limiting equivalent conductivity of cation
`Lambda_(_)^(oo) =` limiting equivalent conductivity of anion
Each ion has a fixed value of limiting equivalent conductance irrespective of the nature of the other electrolyte.
