In the Henderson-Hasselbalch equation for a buffer solution, why does the pH remain unchanged upon dilution?

Options

  1. ADilution increases the concentration of the conjugate base.
  2. BDilution decreases the concentration of the weak acid.
  3. CDilution affects the pK a value.
  4. DDilution does not impact the ratio of [Conjugate acid, BH+] to [Base, B].

Correct answer

D. Dilution does not impact the ratio of [Conjugate acid, BH+] to [Base, B].

Step-by-step solution

In the Henderson-Hasselbalch equation, the pH remains unchanged upon dilution because dilution does not impact the ratio of [Conjugate acid, BH+] to [Base, B].
