Chemistry Question on Solutions
Which one of the following is water soluble?
(a) BeSO4
(b) MgSO4
(c) CaSO4
(d) SrSO4
(e) BaSO4
A
Only a and b
B
Only a, b, c
C
Only d and e
D
Only a and e
Answer
Only a and b
Explanation
Solution
The correct answer is (A) : Only a and b.
Solubility of sulphates of group-2 elements decreases down the group. BeSO4 and MgSO4 are appreciably soluble in water. CaSO4, SrSO4 and BaSO4 are practically insoluble in water.
