Equilibrium Question 200
Question: If $ S $ and $ K _{sp} $ are respectively solubility and solubility product of a sparingly soluble binary electrolyte, then [CPMT 1988; MP PMT 1999]
Options:
A) $ S=K _{sp} $
B) $ S=K_sp^{2} $
C) $ S=\sqrt{K _{sp}} $
D) $ S=\frac{1}{2}K _{sp} $
Show Answer
Answer:
Correct Answer: C
Solution:
For a binary electrolyte, so that $ K _{sp}=S\times S=S^{2} $
$ S=\sqrt{K _{sp}} $ .
