MCQ
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
  • $S_1$ is wrong and $S_2$ is correct
  • B
    Both $S_1$ and $S_2$ are wrong
  • C
    $S_1$ is correct and $S_2$ is wrong
  • D
    Both $S_1$ and $S_2$ are correct

Answer

Correct option: A.
$S_1$ is wrong and $S_2$ is correct
a
We know that

$\lambda _m=\frac {K}{C}$    Here  $\lambda _m\,=$ molar conductivity

                                                     $K=$ conductivity

                                                     $C\,=$ concentration

when concentration increase conductivity always increases. The molar conductivity always  increase wih the  decrease in the concentration
