Explanation:
Sodium sulphate (Na2SO4) and barium sulphate (BaSO4) are both ionic compounds, but they have different solubility properties in water.
1. Solubility of Sodium Sulphate (Na2SO4):
- Sodium sulphate is soluble in water. When Na2SO4 is added to water, it dissociates into its constituent ions: 2Na+ and SO42-.
- The solubility of Na2SO4 can be explained by the hydration energy of the ions. The hydration energy is the energy released when water molecules surround and stabilize the dissolved ions.
- In the case of Na2SO4, the hydration energy of the Na+ and SO42- ions is greater than the lattice energy of Na2SO4. The lattice energy is the energy required to break apart the crystal lattice structure of the compound.
- This means that the hydration energy of Na2SO4 is sufficient to overcome the lattice energy, allowing the compound to dissolve in water.
2. Insolubility of Barium Sulphate (BaSO4):
- Barium sulphate is insoluble in water. When BaSO4 is added to water, it does not dissociate into its constituent ions to a significant extent.
- The insolubility of BaSO4 can be explained by the lattice energy of the compound. The lattice energy of BaSO4 is greater than the hydration energy of the Ba2+ and SO42- ions.
- This means that the lattice energy of BaSO4 is so strong that it cannot be overcome by the hydration energy, preventing the compound from dissolving in water.
Summary:
- The solubility or insolubility of ionic compounds in water is determined by the balance between the hydration energy of the ions and the lattice energy of the compound.
- Sodium sulphate (Na2SO4) is soluble in water because the hydration energy of the ions is greater than the lattice energy of the compound.
- Barium sulphate (BaSO4) is insoluble in water because the lattice energy of the compound is greater than the hydration energy of the ions.
Therefore, option D is correct: Both the hydration energy of Na2SO4 being more than its lattice energy and the lattice energy of BaSO4 being more than its hydration energy explain the solubility difference between sodium sulphate and barium sulphate.
