Among the sulphates of alkaline earth metals, the solubilities of BeSO4 and MgSO4 in water, respectively, are :

Multiple Choice Options

  • A poor and poor
  • B poor and high
  • C high and poor
  • D high and high

Step-by-Step Verified Solution

Order of solubility of sulphate of Alkaline earth metals

BeSO4 > MgSO4 > CaSO4 > SrSO4 > BaSO4

The greater hydration enthalpies of Be2+ and Mg2+ ions dominate over their lattice enthalpies and therefore their sulphates are highly soluble.
