NEET Chemistry pH & Buffer Solutions Assertion Reason Question
Assertion (A): The pH of a solution formed by mixing acetic acid and ammonium hydroxide is determined by the difference in their pK values. | Reason (R): The degree of hydrolysis of salts formed from weak acids and weak bases is independent of the concentration of the solution.
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 pH of a solution formed from a weak acid and weak base is determined by the difference in their pK values as mentioned in the NCERT context. The degree of hydrolysis being independent of concentration supports this assertion.
