Sodium sulphate is soluble in water whereas barium sulphate is sparingly soluble because i the hydration energy of Na SO4 is less than its lattice energy ii the hydration energy of Na SO4 is more than its lattice energy iii the lattice energy of BaSO4 is more than its hydration energy iv the lattice energy has no role to play in solubility 1 i ii 2 ii iii 3 iii iv 4 ii iv
