Chemical buffers are important to industrial production and Buffers are effective at resisting pH changes when large
to living systems. amounts of acid or base are added to a solution.
Chemical buffers have specific ranges and capacities. The buffer capacity is the pH range that is maintained when
acids and bases are added to a solution.
