Equilibrium Question 156
Question: Which is the correct representation of the solubility product constant of $ Ag_2CrO_4 $ [NCERT 1974, 75]
Options:
A) $ {{[A{g^{+}}]}^{2}},[CrO_4^{-2}] $
B) $ [A{g^{+}}][CrO_4^{-2}] $
C) $ [2A{g^{+}}][CrO_4^{-2}] $
D) $ {{[2A{g^{+}}]}^{2}}[CrO_4^{-2}] $
Show Answer
Answer:
Correct Answer: A
Solution:
$ Ag_2CrO_4 $ ⇌ $ [2A{g^{+}}]+[CrO_4^{-,-}] $ Hence $ K _{sp}={{[A{g^{+}}]}^{2}}[CrO_4^{-,-}] $
