Question

Which of the following decreases on dilution of electrolyte solution?

• A. Equivalent conductance
• B. Molar conductance
• C. Specific conductance
• D. Conductance

Answer 1

The correct option is B Molar conductance

Conductance $=\frac{kA}{l}$

where, $k$ is conductivity

$k=K\times G$

where, $K$ is cell constant

Does not depend on the volume of the solution but molar conductance.

${\wedge }_m=\frac{K}{C}$

$C$ is concentration which depends on volume. Hence, affected by dilution.
