Factors affecting buffering capacity
Webbuffering system centered around pH 4.75. Generally, the pK a of a weak acid or base indicates the pH of the center of the buffering region. The terms pK and pK a are frequently used interchangeably in the literature. The term pK a (“a” refers to acid) is used in circumstances where the system is WebAcid buffering capacity and alkali buffering capacity. I determined the buffering capacity value on the basis of the area limited by the titration curve. To perform the calculations on the diagram besides the titration curve of the analyzed sample I made two more that formed the basis for the comparison. One was the
