For the dissolution of NH4NO3, which is greater, the lattice energy or the hydration energy?

For the dissolution of NH₄NO₃, which is greater, the lattice energy or the hydration energy?

Solutions

Expert Solution

Ans :-

Lattice energy :- Amount of energy released when a crystalline solid is formed from its constituent ions.

Hydration energy :- Amount of energy released on dilution of one mole of gaseous ions.

# If Hydration energy > lattice nergy, then compound will be soluble in water.

# If Hydration energy < lattice nergy, then compound will be insoluble in water.

Ammonium nitrate (NH₄NO₃) is soluble in water as all the nitrate salts are soluble in water, therefore hydration energy will be greater than lattice energy.

Therefore, for the dissolution of NH₄NO₃ the hydration energy will be greater than lattice energy.
