Vedclass · Answer

(A) The extent of hydration depends on the size of the ion; the smaller the size of the ion,the higher is its degree of hydration.Among the given alkali metals,$Li^+$ has the smallest ionic size.Due to its small size,$Li^+$ possesses the highest charge density and the highest polarising power.Consequently,it attracts water molecules more strongly than other alkali metals,leading to the formation of hydrated salts such as $LiCl \cdot 2H_2O$.The other alkali metals $(Na, K, Rb, Cs)$ have larger ionic radii and lower charge densities,and therefore,they generally do not form hydrated salts.

Which one of the following alkali metals gives hydrated salts?
