In which of the following the hydration energy is higher than the lattice energy?

Options

  1. AMgSO ₄
  2. BRaSO ₄
  3. CSrSO ₄
  4. DBaSO ₄

Correct answer

A. MgSO ₄

Step-by-step solution

The solubility of sulphates of alkaline earth metals decreases with group from Be to Ba due to the ionic size increases down the group. BeSO ₄ > MgSO ₄ > CaSO ₄ > SrSO ₄ > BaSO ₄ Related Theory The greater the lattice enthalpy, the stronger the forces between ions. Those forces are only completely broken when the ions are present as gaseous ions, scattered so far apart that there is negligible attraction between them. I Caution The lattice energy remains constant because sulphate ion is so large, so that small chan
