Question

The molar conductivity is maximum for the solution of concentration

• A. 0.005 M
• B. 0.004 M
• C. 0.001 M
• D. 0.002

Answer 1

The Correct Option is C

The molar conductivity of an electrolyte solution generally increases with decreasing concentration. Therefore, the solution of the lowest concentration among the given options would have the maximum molar conductivity.
Among the options provided, the solution of concentration (C) 0.001 M would have the highest molar conductivity.
So, the correct answer is (C) 0.001 M.

Answer 2

Molar conductivity (Λ_m) increases as the concentration of the electrolyte decreases. This is because at lower concentrations, the ions experience less interionic attraction and can move more freely, increasing conductivity per mole of electrolyte.

Among the given concentrations, 0.001 M is the most dilute solution and thus has the highest molar conductivity.

Correct Answer: 0.001 M
