The molar conductance of $ ext{NaCl}$, $ ext{HCl}$ and $ ext{CH}_3 ext{COONa}$ at infinite dilution are $1

Question

The molar conductance of $	ext{NaCl}$, $	ext{HCl}$ and $	ext{CH}_3	ext{COONa}$ at infinite dilution are $126.45$, $426.16$ and $91.0 	ext{ S cm}^2 	ext{ mol}^{-1}$ respectively. The molar conductance of $	ext{CH}_3	ext{COOH}$ at infinite dilution is. Choose the right option for your answer.

Accepted Answer

According to Kohlrausch law of independent migration of ions. $\Lambda_m^o(	ext{CH}_3	ext{COOH}) = \Lambda_m^o(	ext{CH}_3	ext{COONa}) + \Lambda_m^o(	ext{HCl}) - \Lambda_m^o(	ext{NaCl}) = 91.0 + 426.16 - 126.45 = 390.71 	ext{ S cm}^2 	ext{ mol}^{-1}$
