The pH of a buffer solution depends on the ratio of the concentrations of the weak acid (or base) and its conjugate base (or acid), not the absolute concentrations themselves. This relationship is described by the Henderson-Hasselbalch equation, where pH = pKa + log([conjugate base]/[weak acid]).
The pH of the buffer solution depends upon the concentration of?
