Vedclass · Answer

(B) The conductivity of ions in an aqueous solution depends on their hydrated ionic size.As the size of the gaseous ion decreases,the extent of hydration increases,which leads to a larger hydrated ionic radius.Larger hydrated ions experience greater resistance (viscous drag) while moving through the solvent,resulting in lower ionic mobility and lower conductivity.The order of gaseous ionic size is: $Cs^{+} > Rb^{+} > K^{+} > Na^{+}$.Consequently,the order of hydrated ionic size is: $Cs^{+} Therefore,the order of ionic conductivity in water is: $Cs^{+} > Rb^{+} > K^{+} > Na^{+}$.

The correct order of conductivity of ions in water is
