Commonly used buffers in the laboratory
WebBuffer preparation is a common process in chemistry and biochemistry laboratories. A buffer solution is a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid. Buffer solutions are used to help maintain a stable pH value of another solution that is mixed with the buffer. WebJan 30, 2024 · Buffer solutions have a working pH range and capacity which dictate how much acid/base can be neutralized before pH changes, and the amount by which it will change. Preparing Buffer Solutions When it comes to buffer solution one of the most common equation is the Henderson-Hasselbalch approximation. An important point that …
