JEE Main 2020 — S Block Elements Question with Solution
From: JEE Main 2020 (Online) 6th September Morning Slot
Question
Among the sulphates of alkaline earth metals,
the solubilities of BeSO4 and MgSO4 in water,
respectively, are :
Choose an option
Show full solutionCorrect option: D
Correct answer
Dhigh and high
Step-by-step explanation
Order of solubility of sulphate of Alkaline earth metals
BeSO4 > MgSO4 > CaSO4 > SrSO4 > BaSO4
The greater hydration enthalpies of Be2+ and Mg2+ ions dominate over their lattice enthalpies and therefore their sulphates are highly soluble.
BeSO4 > MgSO4 > CaSO4 > SrSO4 > BaSO4
The greater hydration enthalpies of Be2+ and Mg2+ ions dominate over their lattice enthalpies and therefore their sulphates are highly soluble.
