WebJun 19, 2024 · The ability of a buffer solution to resist large changes in pH has a great many chemical applications, but perhaps the most obvious examples of buffer action are to be found in living matter. If the pH of human blood, for instance, gets outside the range 7.2 to 7.6, the results are usually fatal. WebBuffer solutions certainly have a massive range of applications. The applications of buffer solutions are for both the real world and the lab. A buffered pH is a necessity of most enzymes to function efficiently and correctly. Furthermore, buffering is important for ensuring proper colour concentration when using dyes.
