AIPMT MAIN 2008 Chemistry Le Chatelier's Principle MCQ Question
Type: MCQ-conceptual-Medium-Class 11
If the concentration of OH⁻ ions in the reaction Fe(OH)₃ (s) ⇌ Fe³⁺ (aq) + 3OH⁻ (aq) is decreased by 1/4 times, then equilibrium concentration of Fe³⁺ will increase by
A
4 times
B
8 times
C
16 times
D
64 times
Correct Answer
Option D
Detailed Explanation
Decreasing OH⁻ concentration shifts the equilibrium to the right, increasing Fe³⁺ concentration. Since OH⁻ is cubed in the equilibrium expression, Fe³⁺ increases by 16 times.
