Vedclass · Answer

(B) The equivalent conductance $(\Lambda_{eq})$ at infinite dilution depends on the ionic mobility of the ions in the solvent. In water, $H^{+}$ and $HO^{-}$ ions exhibit exceptionally high ionic mobilities due to the Grotthuss mechanism (proton hopping). Among the given ions, $H^{+}$ has the highest mobility, followed by $HO^{-}$. $K^{+}$ is a simple hydrated cation with moderate mobility, while $CH_{3}COO^{-}$ is a large polyatomic anion with relatively lower mobility. Therefore, the correct order of equivalent conductances at infinite dilution is $H^{+} > HO^{-} > K^{+} > CH_{3}COO^{-}$.

The correct order of equivalent conductances at infinite dilution in water at room temperature for $H^{+}$, $K^{+}$, $CH_{3}COO^{-}$ and $HO^{-}$ ions is
