WebMar 20, 2024 · Here the line for log (β/ln10) bends up again and passes the crossing point 0.3 units higher. Then the line for log (β/ln10) will follow the line for log [OH-] to pH = 14. From this example, we can immediately identify a local maximum for the buffer capacity, i.e. at pH = pka. From the diagram, we can also identify two local minima, which ... WebFigure 7.2.2: Effect of Buffer Concentration on the Capacity of a Buffer. A buffer maintains a relatively constant pH when acid or base is added to a solution. The addition of even …

Origins Many authors agree that the term buffer … WebThis is the buffer zone. However, once the curve extends out of the buffer region, it will increase tremendously when a small amount of acid or base added to the buffer system. If too much acid is added to the buffer, or if the concentration is too strong, extra protons remain free and the pH will fall sharply. This effect demonstrates the ...
