MHT CET 2023 Chemistry question

What happens when solution of an electrolyte is diluted?

(A)Both and k increases
(B)Both and k decreases
(C) increases and k decreasesCorrect
(D) decreases and k increases

Answer: (C)

Solution

Conductivity ( or k) is the conductance of a unit volume of solution; on dilution the number of ions per unit volume falls, so conductivity decreases. Molar conductivity increases on dilution because the fall in concentration is
