Question

Among Lithium and Beryllium which has
more Hydration Enthalpy

Answer 1

Answer:

The heat energy released when new bonds are made between the ions and water molecules is known as the hydration enthalpy of the ion.

If the hydration enthalpy of an ion is high, it means that the hydrated ion is very stable.

>> Thus, more the attraction, more is hydration, more will be hydration enthalpy.

>>If positive charge density is large, there will be more attraction and hence more hydration enthalpy.

Hence we can say hydration enthalpy is

1).Directly proportional to charge

2).Inversely proportional to size.

For group 1 elements, charge is constant (single positive charge). Hence, hydration enthalpy is inversely proportional to size. Size increases as we go down the group due to addition of more shells.

Hence we can say that hydration enthalpy is maximum for lithium cation amongst the group 1 elements.

I hope it helps.
