Give reasons of the following:
The crystalline salts of alkaline earth metals contain more water of crystallisation than the corresponding alkali metal salts.
The crystalline salts of alkaline earth metals contain more water of crystallisation than the corresponding alkali metal salts.
Alkaline earth metals have a smaller size and higher charge than alkali metals, leading to a greater attraction for water molecules.
Alkali metals readily lose water molecules due to their weaker polarizing power.
Alkaline earth metal ions have a higher hydration enthalpy than alkali metal ions.
The higher charge density of alkaline earth metal ions enhances their ability to coordinate with water molecules.
Alkali metal salts are generally more soluble and thus require less water of crystallization.
