Ion buffer

WebFigure 4 shows an acetic acid-acetate ion buffer as base is added. The initial pH is 4.74. A change of 1 pH unit occurs when the acetic acid concentration is reduced to 11% of the acetate ion concentration. Figure 4. The graph, an illustration of buffering action, ... WebIn continuous buffer systems, the composition of the gel buffer and running buffer are essentially identical throughout the gel. They consist of a single separating gel and use the same buffer ions at the same pH throughout the sample, gel, and electrode reservoirs.
