WebJan 17, 2024 · Buffer solutions keep the pH constant in a wide variety of chemical actions. A buffer solution is a mixture of a weak acid and its conjugate base, or a weak base and its conjugate acid. The bicarbonate buffering system maintains optimal pH levels and regulates the carbon dioxide concentration that, in turn, shifts any acid–base imbalance. ... WebIn biological experiments, it is important to maintain the pH of the solutions used. Buffers, mixtures of appropriate weak acids, and their conjugate bases, are usually used. Most biological reactions occur at a neutral pH, from 6 to 8; the buffer needs to be effective in this range. Furthermore, the acids and bases used in the buffer should ...
