Key Concepts

Buffer Solution

A buffer solution is designed to resist changes in pH when small amounts of acid or base are added. It usually consists of a weak acid and its conjugate base or a weak base and its conjugate acid, which exist in equilibrium and can neutralize added H+ or OH– without a significant shift in pH.

Weak Acid and Conjugate Base Pair

For a solution to function effectively as a buffer, it must contain a weak acid and its conjugate base. The weak acid partially dissociates in solution, and its equilibrium with its conjugate base helps maintain a relatively constant pH. This equilibrium is essential because it allows the buffering species to react in either direction depending on whether acid or base is added.

Neutralization with Strong Acids and Bases

When a strong acid like HCl is mixed with a strong base like NaOH, they react completely through a neutralization reaction to form water and a salt. This total reaction does not leave any significant amount of the original species in equilibrium, nor does it produce a weak acid or base that can act as a buffer. Without this equilibrium, the solution lacks the capacity to counteract further additions of acid or base, hence it is not a buffered solution.
