Explain why mgSo4 is soluble in water but BaSo4 is insoluble

Answers

Answered by Sai1111

Lattice enthalpy of MgSO4 > that of BaSO4 (I dont consider the negative signs)
Hydration enthalpy of MgSO4 > that of BaSO4(negative values as well)
Enthalpy of solution = hydration enthalpy - lattice enthalpy
Hydration enthalpy changes more rapidly than lattice enthalpy -> MgSO4 is more soluble.
