S Block Elements Question 202
Question: Which of the following sulphates have the highest solubility in water
[EAMCET 1980,84,85; MP PMT 1994; Kurukshetra CEE 1998; AFMC 1990; MP PET 1994]
Options:
A) $ MgSO_4 $
B) $ BaSO_4 $
C) $ CaSO_4 $
D) $ BeSO_4 $
Show Answer
Answer:
Correct Answer: D
Solution:
$ BeSO_4 $ is most soluble because hydration energy is more than lattice energy. $ \xrightarrow[Hydration\ energy\ decreases\ hence,\ solubility\ decreases.]{BeSO_4>MgSO_4>CaSO_4>SrSO_4>BaSO_4} $
