WebNov 4, 2024 · Corrosionpedia Explains Buffer Capacity. The main purpose of buffers is to maintain the pH of solutions in a narrow range. In the buffer system, the higher the levels of HA and A - molecules available, the less effect in the pH system when adding a strong base or acid. Even though the pH buffer is identified by the ratio of HA and A -, the ... WebJan 30, 2024 · A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base, thus maintaining the pH of the solution relatively stable. This is important for processes and/or reactions which require specific and stable pH ranges.
