FAQs

1. Why do buffer solutions resist changes in pH even after adding strong acids or bases?

Buffer solutions resist pH changes because they contain a weak acid and its conjugate base (or vice versa), which neutralize added H⁺ or OH⁻ ions. When a strong acid is added, the base component of the buffer reacts with the excess hydrogen ions. When a strong base is introduced, the acid component donates hydrogen ions to neutralize the hydroxide ions. This dynamic equilibrium allows the solution to maintain a relatively stable pH.

2. Why does the buffering capacity weaken when a buffer is too diluted or overly concentrated?

Buffering capacity diminishes when the buffer is too diluted because there are fewer acid-base pairs available to neutralize added acids or bases. Conversely, an overly concentrated buffer can affect the ionic strength of the solution, potentially interfering with biological or chemical reactions. Maintaining an appropriate concentration ensures that the buffer can effectively stabilize the pH without unintended side effects.

3. Is it possible to make a buffer solution with a strong acid or base?

No, buffer solutions require a weak acid and its conjugate base or a weak base and its conjugate acid because strong acids and bases dissociate completely in water and do not establish the equilibrium necessary to resist pH changes. For example, acetic acid and sodium acetate form a buffer, but hydrochloric acid (a strong acid) cannot form a buffer with sodium chloride.

4. What happens if you exceed a buffer's capacity during a chemical reaction?

If you exceed a buffer’s capacity, the solution will no longer maintain a stable pH because all available acid or base components are used up. As a result, the pH can shift sharply in response to further addition of acids or bases. This is called "buffer exhaustion," and it can lead to inaccurate results or the failure of pH-sensitive reactions in chemical or biological systems.

5. Can a buffer solution be reused in multiple experiments, or does it degrade over time?

While buffer solutions can sometimes be reused, their effectiveness may degrade over time due to contamination, evaporation, or pH drift. Exposure to air, repeated use, or microbial growth can alter the concentration of buffering components. It’s best practice to prepare fresh buffer solutions or store them properly in sterile, sealed containers if reuse is intended.
