Vedclass · Answer

(A) Conductivity $(K)$ is defined as the conductance of a unit volume of solution. As the concentration of an electrolyte decreases,the number of ions per unit volume decreases,leading to a decrease in conductivity. Thus,$S_1$ is incorrect.Molar conductivity $(\lambda_m)$ is defined as $\lambda_m = \frac{K}{C}$. As the concentration $(C)$ decreases,the volume of solution containing one mole of electrolyte increases significantly,which outweighs the decrease in conductivity $(K)$. Consequently,molar conductivity increases with a decrease in concentration. Thus,$S_2$ is correct.

Consider the statements $S_1$ and $S_2$:
$S_1$: Conductivity always increases with decrease in the concentration of electrolyte.
$S_2$: Molar conductivity always increases with decrease in the concentration of electrolyte.
The correct option among the following is
