Question: Solubility of a salt $ M_2X_3 $ is $ ymol,d{m^{-3}}. $ The solubility product of the salt will be [IIT 1990, 97; AFMC 1991; RPMT 1999; MP PET 2001; MP PMT 2003; Orissa JEE 2005]
Options:
A) $ 6y^{4} $
B) $ 64y^{4} $
C) $ 36y^{5} $
D) $ 108y^{5} $
Show Answer
Answer:
Correct Answer: D
Solution:
$ \underset{K _{sp}}{\mathop{M_2X_3}}, $ ⇌ $ \underset{{{(2y)}^{2}}}{\mathop{2{M^{+++}}}}, $ + $ \underset{{{(3y)}^{3}}}{\mathop{3{X^{–}}}}, $ Solubility product $ K _{sp}=108y^{5},mol\frac{d}{m^{3}} $
