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` conductivity increases, in `B` conductivity decrease

B

In `A` conductivity decreases while, in `B` conductivity decrease

C

In both `A` and `B` conductivity increases

D

In both `A` and `B` conductivity decreases

Text Solution

Verified by Experts

The correct Answer is:
c

For strong and weak electrolytes, increasing concentration will increase conductance `(G)`, decrease molar conductance `(wedge_(m))` and equivalent conductance `(wedge_(eq))` and inceases conductivity `(k)`.

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 ?
