What is solubility order of sulphate of alkaline earth metal?

The solubility order of alkaline earth metal sulfates generally decreases as you move down the group in the Periodic Table. Thus, the solubility trend is: magnesium sulfate (MgSO₄) and calcium sulfate (CaSO₄) are relatively soluble, while strontium sulfate (SrSO₄) is moderately soluble, and barium sulfate (BaSO₄) is largely insoluble. Therefore, the overall order of solubility from most to least soluble is MgSO₄ > CaSO₄ > SrSO₄ > BaSO₄.
