A buffer solution resists large pH changes when diluted or mixed with acid/base.

When strong acid is added to a buffer, the equilibrium shifts, reducing the hydrogen ions.

In a buffer, weak acid and its conjugate base create a balance resisting pH changes.

Living systems, like blood and oceans, use buffering for pH control.

Adding a small amount of strong base to a buffer has minimal impact on pH.

The main characteristic of a buffer solution is its ability to resist changes in pH when an acid or a base is added.

When a strong acid is added to a buffer solution, the pH resists change because the excess hydrogen ions (H+) react with the conjugate base to form the weak acid, thereby minimizing the pH change.

The weak acid and its conjugate base in a buffer solution work together to maintain a relatively constant pH by reacting with added acids or bases to neutralize their effects.

Buffering is used for pH regulation in various living systems, including blood plasma, where it helps maintain a narrow pH range necessary for proper cellular function.

When a small amount of strong base is added to a buffer solution, the pH remains relatively constant because the hydroxide ions (OH-) react with the weak acid to form water, minimizing the pH change.
