Archived from the original on These buffers were developed with the following criteria in mind: midrange p K amaximum water solubility and minimum solubility in all other solventsminimal salt effects, minimal change in p K a with temperature, chemically and enzymatically stable, minimal absorption in visible or UV spectral range and reasonably easily synthesized.
The pH value can tell you whether you're dealing with an acid or a base, but it offers limited value indicating the true strength of the acid of a base. Malic acid is the main acid in many fruits, including apricotsblackberriesblueberriescherriesgrapesmirabellespeachespearsplumsand quince  and is present in lower concentrations in other fruits, such as citrus.

They describe the degree of ionization of an acid or base and are true indicators of acid or base strength because adding water to a solution will not change the equilibrium constant.
It is the pH at which a protein or another molecule is electrically neutral has no net electrical charge. Weinheim: Wiley-VCH.
