Equilibrium Question 194
Question: If the solubility of a sparingly soluble salt of the type $ BA_2 $ (giving three ions on dissociation of a molecule) is $ x $ moles per litre, then its solubility product is given by [BHU 1987]
Options:
A) $ x^{2} $
B) $ 2x^{3} $
C) $ 4x^{2} $
D) $ 4x^{3} $
Show Answer
Answer:
Correct Answer: D
Solution:
By formula $ BA_2\to {B^{+}}+2{A^{-}} $
$ K _{sp}=4x^{3} $
