Question

Correct the following statement:

For a strong electrolyte, the plot of equivalent conductance versus concentration of the solution is a straight line.

Answer 1

Corrected Statement: For a strong electrolyte, the plot of equivalent conductance versus the square root of concentration `(sqrt C​)` is a straight line.

Explanation:
According to Kohlrausch’s law, for strong electrolytes, equivalent conductance decreases linearly with `(sqrt C​)` due to increased interionic interactions at higher concentrations. Hence, a straight-line graph is obtained when Λ_eq​ is plotted against `(sqrt C​)`​, not directly against C.
