Equilibrium Question 147
Question: The expression for the solubility product of $ Al_2,{{(SO_4)}_3} $ is
Options:
A) $ K _{sp}=[A{l^{3+}}](SO_4^{2-}] $
B) $ K _{sp}={{[A{l^{3+}}]}^{2}}{{(SO_4^{2-}]}^{3}} $
C) $ K _{sp}={{[A{l^{3+}}]}^{3}}{{(SO_4^{2-}]}^{2}} $
D) $ K _{sp}={{[A{l^{3+}}]}^{2}}{{(SO_4^{2-}]}^{2}} $
Show Answer
Answer:
Correct Answer: B
Solution:
Solubility of $ Al_2{{(SO_4)}_3} $
$ Al_2{{(SO_4)}_3} $ ⇌ $ 2A{l^{+++}}+3SO_4^{-,-} $
$ K _{sp}={{[A{l^{3+}}]}^{2}},{{[SO_4^{2-}]}^{3}} $
