Which of the following mixture will constitute the buffer solution?
Correct answer: A. Acetic acid & sodium acetate
- A. Acetic acid & sodium acetate
- B. Acetic acid & ammonia
- C. Acetic acid and its ammonium acetate
- D. Ammonia & ammonium acetate
Explanation
.Acetic acid acts a good buffer with its salt because it is a weak acid.Acetic acid and sodium acetate form a buffer solution due to their ability to resist changes in pH when small amounts of acids or bases are added.

About Buffer Solutions
Buffer solutions resist changes in pH when small amounts of acid or base are added, using a weak acid and its conjugate base or a weak base and its conjugate acid. Work includes buffer action, the common-ion effect, Henderson-Hasselbalch calculations, buffer capacity, and the difference between acidic and basic buffers.
