ABSTRACT
Buffers play a significant role in the world around us. For instance, the buffer qualities of soil are important in keeping the pH relatively constant. If the pH were to drop, the organisms living in the soil would not be able to maintain life. This includes plants that are harvested for food! Also, our blood uses buffer systems to maintain a constant pH within our body between 7.35 and 7.45. Even small variations from this range will cause physiological problems.
