8.9 Buffer Capacity and Buffer Range - Chemistry LibreTexts
Buffers are characterized by the pH range over which they can maintain a more or less constant pH and by their buffer capacity, the amount of strong acid or base that can be absorbed before the pH changes significantly. Although the useful pH range of a buffer depends strongly on the chemical properties of the weak acid … 展开
Buffers function best when the pKa of the conjugate weak acid used is close to the desired working range of the buffer. This turns out to be the case … 展开
