Ph of an acidic buffer mixture is

WebA buffer is a solution that resists a change in pH upon the addition of acidic or basic components. To effectively maintain a pH range, a buffer consists of a weak conjugate acid-base pair, meaning either a weak acid and its conjugate base, or a weak base and its conjugate acid. An acidic buffer solution is the one which has a pH less than 7 ... WebAcetate buffers are used in biochemical studies of enzymes and other chemical components of cells to prevent pH changes that might affect the biochemical activity of these compounds.
