Vedclass · Answer

(D) $1$. According to the Kohlrausch law and the Debye-$H$ückel-Onsager equation, strong electrolytes show a linear relationship between molar conductivity $(\Lambda_m)$ and $\sqrt{c}$ given by $\Lambda_m = \Lambda_m^\circ - A\sqrt{c}$, where $\Lambda_m^\circ$ is the intercept on the y-axis.$2$. Weak electrolytes like $CH_3COOH$, $NH_4OH$, and $HCOOH$ show a non-linear curve that increases sharply as concentration approaches zero.$3$. $CH_3COONa$ is a strong electrolyte, which dissociates completely in solution, thus following the linear relationship.$4$. Therefore, '$X$' is $CH_3COONa$.

The graphical variation of molar conductivity $(\Lambda_m)$ against the square root of molar concentration $(\sqrt{c})$ for a certain electrolyte '$X$' is linear with an intercept on the y-axis. Identify '$X$' from the following.
