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