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{b^{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 $ S{b^{3+}} $ and $ B{i^{3+}} $ is very low and $ C{l^{-}} $ is present in high concentration, therefore Sb and Bi get precipitated, as $ S{b^{3+}}+3C{l^{-}}\to SbCl_3 $
