The Substance which resist in change in PH is called?
Correct answer: C. Buffer
- A. Neutralization
- B. Osmosis
- C. Buffer
- D. Active transport
Explanation
A buffer resists a change in pH when small amounts of acid or base are added because its weak acid and conjugate base, or weak base and conjugate acid, neutralize the added material. Neutralization is a reaction, not the substance itself, so that is the likely mistaken option.

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.
