Assertion: `BeSO_(4) and MgSO_(4)` are insoluble in water. Reason: `Be^(2+) and Mg^(2+)` have low hydration enthalpies.A. If both assertion and reason are true and reason is the correct explanation of assertionB. If both assertion and reason are true but reason is not the correct explanation of assertionC. If assertion is true but reason is false.D. If both assertion and reason are false. |
Answer» Correct Answer - D The greater hydration enthalpies of `Be(2+)` and `Mg^(2+)` ions overcome the lattice enthalpy facctor and therefore, their sulphates are soluble in water. |
