Why is the pH of a buffer solution not significantly affected by dilution?

Options

  1. ADilution increases the concentration of the weak acid.
  2. BDilution decreases the concentration of the conjugate base.
  3. CDilution changes the pKa value of the acid.
  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

The pH of a buffer solution is not significantly affected by dilution because dilution does not impact the ratio of [Conjugate acid, BH+] to [Base, B] in the Henderson-Hasselbalch equation.
