Vedclass · Answer

(D) $1$. According to the Kohlrausch law, for strong electrolytes, the variation of molar conductivity $(\Lambda_m)$ with concentration $(c)$ is given by the Debye-$H$ückel-Onsager equation: $\Lambda_m = \Lambda_m^0 - A\sqrt{c}$.$2$. This equation represents a straight line with a negative slope and an intercept equal to $\Lambda_m^0$ on the y-axis.$3$. Weak electrolytes like $CH_3COOH$, $NH_4OH$, and $HCOOH$ show a non-linear increase in $\Lambda_m$ with dilution, especially at low concentrations.$4$. $CH_3COONa$ is a strong electrolyte, which follows the linear relationship.$5$. 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.
