Question

For strong electrolytes λ_m: 

(A) Increases on dilution 

(B) Decreases on dilution 

(C) remains constant on dilution 

(D) All of these

Answer 1

Correct Answer is: (B) Decreases on dilution 

For strong electrolytes λ_m increases slowly with dilution but for weak electrolytes λm increases steeply on dilution.Molar conductivity increases with decrease in concentration because both the number of ions as well as the mobility of increase with dilution.
