Analytical Chemistry Question 109
Question: A solution prepared in conc. $ HCl $ sometimes gives white turbidity even in the absence of 1st group, when water is added to it. It is due to the presence of
Options:
A) $ H{g^{2+}} $
B) $ S{Fe^{3+}} $
C) $ A{g^{3+}} $
D) $ S{b^{3+}} $ or $ B{i^{3+}} $ or both
Show Answer
Answer:
Correct Answer: D
Solution:
As the ionic product of $ Sb^{3+} $ and $ Bi^{3+} $ is very low and $ Cl^{-} $ is present in high concentration, therefore Sb and Bi get precipitated, as $ Sb^{3+}+3Cl^{-}\to SbCl_3 $
