Citric acid is a weak tricarboxylic acid found in citrus fruits like lemons, which contain 7-9% citric acid according to their dry weight. The three carboxylate groups of citric acid monohydrate have different pKa values, namely 3.15, 4.78, and 6.40 [ 7 ]. Until 1919, lemons were the main source of citric acid ( Figure 1 ).

A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base, thus maintaining the pH of the solution relatively stable. This is important for processes and/or reactions which require specific and stable pH ranges.

Phosphate-buffered saline (PBS) is a buffer solution (pH ~ 7.4) commonly used in biological research.It is a water-based salt solution containing disodium hydrogen phosphate, sodium chloride and, in some formulations, potassium chloride and potassium dihydrogen phosphate.The buffer helps to maintain a constant pH. The osmolarity and ion concentrations of the solutions match those of the human.
