Which factor primarily determines the solubility of alkaline earth metal sulfates in water?

Options

  1. ALattice enthalpy
  2. BHydration enthalpy
  3. CIonic radius
  4. DElectron configuration

Correct answer

B. Hydration enthalpy

Step-by-step solution

The solubility of alkaline earth metal sulfates in water is primarily determined by the hydration enthalpy of the metal ions. Higher hydration enthalpies favor greater solubility in water.
