Q. Kohlrausch's law states that at
A) Infinite dilution, each ion makes definite contribution to equivalent conductance of an electrolyte, whatever be the nature of the other 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 definite 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
Explanation
[Solution from source] Kohlrausch's law of independent migration says that at infinite dilution each ion contributes a fixed amount to the limiting equivalent (or molar) conductivity, whatever the other ion is. It does not hold at finite dilution, where interionic attractions matter, and it is stated for equivalent/molar conductance, not plain conductance. Answer (1).
