Question

The molar conductivity is maximum for the solution of concentration:

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

Answer 1

Answer: (D)

$0.001$M

Molar conductivity is defined as the conductivity of an electrolyte solution divided by the molar concentration of electrolyte.

We know the relation between Molar conductivity and Molarity i.e.

${\Lambda }_m=\frac{\kappa \times 1000}{M}$

$⟹{\Lambda }_m$ is inversely proportional to Molarity

Hence, the solution having maximum molar conductivity has to be less concentrated.

Here, Option D is the one which is having less concentration of all other options and hence is the coreect answer
