Sodium sulphate is soluble in water but barium sulphate is insoluble because
The hydration energy of Na2SO4 is more than its lattice energy
The lattice energy of BaSO4 is more than its hydration energy
The lattice energy has no role to play in solubility
Both (a) and (b)
Solubility of a salt depends on the relative magnitudes of Lattice energy and Hydration energy.
Na2SO4 is soluble in water while BaSo4 is insoluble. Which of the reason is correct about the above statement
