Q17 / 180 · KCET 2022 · Chemistry

The molar conductivity is maximum for the solution of concentration

  • A
    $0.002 \mathrm{M}$
  • B
    $0.005 \mathrm{M}$
  • Correct answer
    C
    $0.001 \mathrm{M}$
  • D
    $0.004 \mathrm{M}$

Solution

We know that, molar conductivity, $\Lambda_{\mathrm{m}}=\frac{\kappa \times 1000}{M}$ That means $\Lambda_{\mathrm{m}}$ is inversely proportional to the molarity. The solution which is less concentrated have maximum molar conductivity. Thus, among the given option $0.001 \mathrm{M}$ has the maximum molar conductivity.

Hence, the correct answer is option: 'C'.
