NEET Chemistry Ionic Equilibrium MCQ Question
Which of the following statements about ionic equilibrium is correct?
In weak electrolytes, equilibrium is established between ions and unionized molecules.
The addition of a strong electrolyte shifts the equilibrium to the right.
Water cannot act as both an acid and a base at the same time.
The common ion effect is unrelated to Le Chatelier's principle.
Correct Answer
Detailed Explanation
Statement A is correct as it highlights the nature of weak electrolytes where equilibrium exists between ions and unionized molecules. Statement B is incorrect because adding a strong electrolyte typically shifts the equilibrium to the left. Statement C is false; water can act as both an acid and a base simultaneously. Statement D misrepresents the common ion effect, which is indeed based on Le Chatelier's principle.
