Equilibrium Question 186

Question: If $ K _{sp} $ for $ HgSO_4 $ is $ 6.4\times {10^{-5}}, $ then solubility of the salt is [AFMC 1997; KCET 2000; CPMT 2000; JIPMER 2001]

Options:

A) $ 8\times {10^{-3}} $

B) $ 8\times {10^{-6}} $

C) $ 6.4\times {10^{-5}} $

D) $ 6.4\times {10^{-3}} $

Show Answer

Answer:

Correct Answer: A

Solution:

$ HgSO_4 $ of $ K _{sp}=S^{2} $

$ S=\sqrt{K _{sp}} $ ; $ S=\sqrt{6.4\times {10^{-5}}} $ ; $ S=8\times {10^{-3}} $ m/l.
