NEET Chemistry Ionic Equilibrium Assertion Reason Question
Assertion (A): The presence of a common ion suppresses the ionization of a weak electrolyte. | Reason (R): The common ion effect is explained by Le Chatelier’s principle.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
Detailed Explanation
The common ion effect leads to a shift in the equilibrium of a weak electrolyte's ionization, as predicted by Le Chatelier’s principle. Adding an ion already present in the solution reduces further ionization.
