NEETChemistrys Block Elements
Why are BeSO 4 and MgSO 4 readily soluble in water while CaSO 4 , SrSO 4 , and BaSO 4 are insoluble?
Options
- ABecause Be +2 and Mg +2 have low hydration enthalpy.
- BDue to the high lattice energy of CaSO 4 , SrSO 4 , and BaSO 4 .
- CBecause Ca +2 , Sr +2 , and Ba +2 have high hydration enthalpy.
- DBeSO4 and MgSO4 are less dense than CaSO 4 , SrSO 4 , and BaSO 4 .
Correct answer
A. Because Be +2 and Mg +2 have low hydration enthalpy.
Step-by-step solution
Correct Option is : (A) Because Be +2 and Mg +2 have low hydration enthalpy.
