Question:
Assertion (A): MgSO4 is readily soluble in water.
Reason (R): The greater hydration enthalpy of Mg2+ ions overcomes its lattice enthalpy.
Assertion (A): MgSO4 is readily soluble in water.
Reason (R): The greater hydration enthalpy of Mg2+ ions overcomes its lattice enthalpy.
Reason (R): The greater hydration enthalpy of Mg2+ ions overcomes its lattice enthalpy.
Show Hint
Solubility depends on hydration enthalpy overcoming lattice enthalpy.

- A and R both are correct and R is the correct explanation of A.
- A and R both are correct but R is not the correct explanation of A.
- A is correct but R is not correct
- A is incorrect but R is correct
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Mg\textsuperscript{2+} has a very high charge density and high hydration enthalpy, which compensates for the lattice energy of MgSO\textsubscript{4}, making it soluble in water.
