Vedclass · Accepted Answer

$CH_3COOH$ is a weak electrolyte,while $CH_3COONa$ is a strong electrolyte.

Vedclass · Answer

(A) $CH_3COOH$ is a weak electrolyte,which undergoes partial dissociation in solution.
On dilution,the degree of dissociation $(\alpha)$ increases significantly according to Ostwald's dilution law,leading to a sharp increase in the number of ions and thus a drastic increase in molar conductivity $(\Lambda_m)$.
$CH_3COONa$ is a strong electrolyte,which is already completely dissociated in solution.
On dilution,the number of ions remains constant,and the increase in $\Lambda_m$ is only due to the decrease in inter-ionic attractions,which results in a gradual increase.

Why on dilution the $\Lambda_m$ of $CH_3COOH$ increases drastically,while that of $CH_3COONa$ increases gradually?
