Analytical Chemistry Question 87
When $ HCl $ gas is passed through saturated solution of $ BaCl_2 $ , a white ppt. is obtained. This is due to the formation of barium sulfate
[CPMT 1979]
Options:
A) Impurities in $ BaCl_2 $
B) Impurities in $ HCl $
C) Precipitation of $ BaCl_2 $ solution
D) Formation of complex compound
Show Answer
Answer:
Correct Answer: C
Solution:
White precipitate obtained is of $ BaSO_4 $ , as the $ Cl^{-} $ ion’s concentration increases due to the addition of HCl, the ionic product becomes more than solubility product and thus, BaSO4 is precipitated
