Question
The right order of the solubility of sulphates of alkaline earth metals in water isBe>Ca>Mg>Ba>SrMg>Be>Ba>Ca>SrBe>Mg>Ca>Sr>BaMg>Ca>Ba>Be>Sr
Solution
The correct order of solubility of sulphates of alkaline earth metals in water is Be > Mg > Ca > Sr > Ba.
Here's why:
-
Beryllium sulphate (BeSO4) is highly soluble in water due to its small size, which allows water molecules to hydrate it effectively.
-
Magnesium sulphate (MgSO4) is also soluble in water, but less so than beryllium sulphate. This is because magnesium ions are larger and therefore less effectively hydrated.
-
Calcium sulphate (CaSO4) is moderately soluble in water. Its larger size compared to magnesium and beryllium makes it less effectively hydrated.
-
Strontium sulphate (SrSO4) is sparingly soluble in water. Its larger size compared to calcium, magnesium, and beryllium makes it less effectively hydrated.
-
Barium sulphate (BaSO4) is insoluble in water. Its large size makes it the least effectively hydrated of the five.
So, the correct order is Be > Mg > Ca > Sr > Ba.
