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.

What is effect of increasing concentration on the molar conductivity of a weak electrolyte ?

Assertion A: The molar conductance of weak electrolyte is low as compared to that of strong electrolytes at moderate concentrations. Reason R: Weak electrolytes at moderate concentrations dissociate to a much greater extent as compared to strong electrolytes.

(i) For a weak electrolyte, molar conductance in dilute solution increases sharply as its concentration in solution is decreased. Give reason.

Why wedge_(m)^(@) for weak electrolyte (e.g., NH_(4)OH or CH_(3)COOH) cannot be determined experimentally ?
