A buffer solution is that which resists/minimizes the change in:
Correct answer: B. pH
- A. pOH
- B. pH
- C. pKa
- D. pKb
Explanation
A buffer solution is a solution that can resist a change in pH upon addition of an acidic or basic component. It contains a weak acid and its conjugate base or a weak base and its conjugate acid. The buffer solution minimizes changes in pH because the weak acid or base reacts with any added acid or base, respectively, to maintain the solution's pH within a relatively narrow range. The buffer solution can only resist a change in pH within a certain range, known as the buffer capacity.
