Consider the statements S1 and S2
S1 : Conductivity always increases with decrease in the concentration of electrolyte.
S2 : Molar conductivity always increases with decrease in the concentration of electrolyte.
The correct option among the following is :
S1 : Conductivity always increases with decrease in the concentration of electrolyte.
S2 : Molar conductivity always increases with decrease in the concentration of electrolyte.
The correct option among the following is :
Show Hint
- Both S1 and S2 are wrong
- S1 is correct and S2 is wrong
- Both S1 and S2 are correct
- S1 is wrong and S2 is correct
The Correct Option is D
Solution and Explanation
S2: Molar conductivity \(\Lambda_m = \frac{\kappa}{c}\). On dilution, \(\kappa\) falls less rapidly than \(c\) (for weak electrolytes the degree of dissociation increases; for strong electrolytes inter-ionic attraction decreases), so \(\Lambda_m\) increases and approaches \(\Lambda_m^\circ\) at infinite dilution. S2 is correct.
So S1 is wrong and S2 is correct.
Answer: (4) S1 is wrong and S2 is correct
