Answer:
It's true.
Explanation:
The systems that are responsible for preventing large variations in pH are called buffers. They are solutions of weak acids and conjugate bases or weak bases and conjugated acids. Buffers resist both the addition of acids and bases.
Buffers have the ability to maintain an almost constant pH when small amounts of acid or base are added. Its ability to regulate the pH is by the amount of acid or base that can be added without destroying the buffer capacity of the buffer and that will depend on the amount of acid or conjugate base it has.
