Assertion (A):- is readily soluble in water Reason (R):- The greater hydration enthalpy of ions overcome its lattice enthalpy.
- A A and R both are correct and R is the correct explanation of A.
- B A and R both are correct but R is not the correct explanation of A.
- C A is correct but R is not correct
- D A is incorrect but R is correct
Answer & Solution
Correct Answer
(A) A and R both are correct and R is the correct explanation of A.
Step-by-step Solution
Detailed explanation
For a compound to be soluble in water, hydration enthapy must dominate over the lattice enthalpy. In MgSO4, Mg2+ being smaller in size, hydration enthalpy dominates over the lattice enthalpy of MgSO4. Hence, MgSO4 is readily soluble in water.
