Explanation: No explanation available. - The solubility of the alkaline earth metal sulphates is slightly increased by the addition of strong acids. I know that, solubility of alkaline earth metal hydroxides increases down the group and solubility of alkaline earth metal sulfates decreases down the group. Hydroxides of the lighter alkaline earth metals are insoluble in water, but their solubility increases as the atomic number of the metal increases. Colours of metal sulfides are important in identifying compounds in inorganic chemistry. Case 1: As we go down the periodic group of alkaline earth metal, the size of atoms increase. Thermal stability of alkali metal hydrides and carbonates (1 answer) Closed 1 year ago. BaSO4 is the least soluble. Statistical critical evaluation of the created databases was produced since there were enough independent data sources to justify such evaluation. Correct Answer: Mg > Ca > Sr > Ba. Lattice energy is constant whereas hydration energy decreases from .
