Buffer solutions are liquids of such composition as to resist appreciable changes in hydrogen ion concentration. Addition of traces of acids or bases leaves their pH practically unaltered. For this reason they are indispensable as comparison media in colorimetric pH determinations.

It is preferable, however, to prepare fresh solutions each month.
