Which of the following statements is correct? a)Molar conductivity of a strong electrolyte decreases with dilution b)Molar conductivity of a strong and weak electrolyte decreases with dilution c)Molar conductivity of a weak electrolyte decreases with dilution d)Molar conductivity of a strong and weak electrolyte increases with dilution

Answer

d)Molar conductivity of a strong and weak electrolyte increases with dilution

Molar conductivity of both weak and strong electrolytes increases as the total volume of solution containing 1 mol of electrolyte increases.

On dilution the volume of solution increases. In case of weak electrolyte, dilution leads to better dissociation of electrolyte into ions by Ostwald dilution theory which leads to an increase in molar conductivity.
