A) 8 times
B) 16 times
C) 64 times
D) 4 times
Correct Answer: C
Solution :
Key Idea: The concentration of solids taken to be unity. \[Fe{{(OH)}_{3}}(s)F{{e}^{3+}}(aq)+3O{{H}^{-}}(aq)\] \[\therefore \]\[K=[F{{e}^{3+}}]{{[O{{H}^{-}}]}^{3}}\] Hence, if \[O{{H}^{-}}\]ion concentration is decreased by \[\frac{1}{4}\]times, then equilibrium concentration of \[F{{e}^{3+}}\]will increase by 64 times.You need to login to perform this action.
