Which of the following correctly defines a buffer?
- A buffer is a substance that increases the pH of a solution by releasing hydrogen ions.
- A buffer is a solution that prevents any change in pH upon the addition of an acid or a base.
- A buffer is a compound that reacts with water to form a weak acid or base, thus stabilizing the pH of a solution.
- A buffer is a solution that resists changes in pH when small amounts of acid or base are added to it. It consists of a weak acid and its conjugate base, or a weak base and its conjugate acid, which react with added H⁺ or OH⁻ ions to minimize changes in pH.
What is #4
