Conductivity , Molar conductivity and Equivalent Conductivity

Question

‘A’ is a strong electrolyte. ‘B’ is a weak electrolyte. Decimolar solutions of ‘A’ and ‘B’ are taken in two separate vessels at same temperature. On diluting both these electrolytes to the same extent, correct statement of the following is

Easy

A

Increase in molar conductance in A will be greater than in B
B

Increase in molar conductance in B will be greater than in A
C

Same magnitude of increase in molar conductance in both A and B
D

Molar conductance is unaffected by dilution in both cases

Solution

Due to dilution,
Electrolyte B….increase in ionization and ionic mobility;
Electrolyte A….increase in ionic mobility only;
Variation is more in B than in A;
