NEET Chemistry pH & Buffer Solutions MCQ Question
Which of the following combinations correctly describes the characteristics of buffer solutions as discussed in the context of pH and buffer solutions?
Buffer solutions can resist changes in pH upon the addition of small amounts of acid or base.
Buffer solutions only consist of strong acids and their salts.
The pH of a buffer solution can be determined using the Henderson–Hasselbalch equation.
Buffer solutions can only be made from weak acids and weak bases.
Correct Answer
Detailed Explanation
Buffer solutions consist of a weak acid and its conjugate base (or vice versa), allowing them to resist changes in pH when small amounts of acid or base are added. The Henderson–Hasselbalch equation helps calculate the pH of these solutions, but strong acids cannot form buffers as they fully ionize.
