Conductivity , Molar conductivity and Equivalent Conductivity

Question

Statement I : At moderate concentrations molar conductivity of KCl is greater than that of CH₃COOH
Statement II : At moderate concentrations, KCl completely ionizes whereas CH₃COOH undergoes incomplete ionisation

Easy

A

Statement I and II are correct
B

Statement I correct and Statement II incorrect
C

Statement - I is incorrect and Statement - II is correct
D

Both statement - I and II are incorrect

Solution

aq. KCl is a strong electrolyte and aq CH₃COOH is a weak electrolyte.
A strong electrolyte completely ionizes even at moderate concentration where as a weak electrolyte cannot completely ionise even at infinite dilution.
Thus at moderate concentrations KCl_(aq) is a better conductor than CH₃COOH_(aq).
Statement I and II are correct.
