Question

Q. Kohlrausch's law states that at
A finite dilution, each ion makes definite contribution to equivalent conductance of an electrolyte, whatever be the nature of the other ion of the electrolyte
B infinite dilution, each ion makes definite contribution to equivalent conductance of an electrolyte depending on the nature of the other ion of the electrolyte
C infinite dilution, each ion makes definite contribution to conductance of an electrolyte, whatever be the nature of the other ion of the electrolyte
(D) infinite dilution, each ion makes definite contribution to equivalent conductance of an electrolyte, whatever be the nature of the other ion of the electrolyte

Answer 1

Solution:
Kohlrausch's law states that "the equivalent conductance of an electrolyte at infinite dilution is equal to the sum of the equivalent conductances of the component ions.
$$
\lambda_{\infty}=\lambda_{a}+\lambda_{c}
$$
where, \(\lambda_{a}=\) equivalent conductance of the anion \(\lambda_{c}=\) equivalent conductance of the cation Each ion has the same constant ionic conductance at a fixed temperature, no matter of which electrolyte it forms a part.
