WebIn chemical and biological systems, buffered solutions are crucial. While another process produces acids or bases, a buffer enables for the preservation of a relatively limited pH range. A buffer can react with either acid or base to remove the acid or base from solution since it is made up of a weak acid and its conjugate base. WebBecause it is essential for many chemical reactions that pH is maintained within a narrow range, biological system employ various buffer systems. Buffers are chemicals that tend to resist changes in ph. Note that buffers do not prevent changes; they resist changes. Let’s see if we can figure out how this works.
