To obeserve the effect of concentration ...

To obeserve the effect of concentration on the conductivity, electrolytes of different natures are taken in two vessels `A` and `B,` A contains weak electrolyte, `e.g., NH_(4)OH` and `B` contains strong electrolyte, `e.g., NaCl`. In both containers, the concentration of respective electrolyte is increased and the conductivity observed`:`

A

In 'A' molar conductivity increases.

B

In 'A' molar conductivity decreases

C

In 'B' molar conductivity increases.

D

In 'B' molar conductivity decreases.
