According to the Henderson-Hasselbalch equation, how does the pH of a buffer solution change when the ratio of weak acid to its conjugate base is increased?

Options

  1. AThe pH decreases
  2. BThe pH increases
  3. CThe pH remains unchanged
  4. DThe pH becomes neutral

Correct answer

C. The pH remains unchanged

Step-by-step solution

According to the Henderson-Hasselbalch equation, when the ratio of weak acid to its conjugate base is increased in a buffer solution, the pH remains unchanged.
