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.
