(a) The solubility of the sulphates decreases down Group 2 because the hydration energies of the ions decrease more rapidly than the lattice energies with increasing ionic size in the order Mg2+ Mg > Ca > Sr > Ba. Oxford Textbook Pages : 157. Solubility is the maximum amount a substance will dissolve in a given solvent. As you go down the group, the energy needed to break up the lattice falls as the positive ions get bigger. Solubility of any compound is decided by its hydration enthalapy and lattice energy.
