The equation KHC8H4O4 + NaOH = NaKC8H4O4 + H2O, which is balanced, illustrates the reaction between KHP and NaOH. The chemical name for potassium hydrogen phthalate, or KHP, is KHC8H4O4.

A positive hydrogen ion and a negative hydrogen atom depart KHC8H4O4 and NaOH, respectively, when KHP and NaOH mix. H2O, the chemical formula for water, is created when these two atoms join forces with the oxygen from the NaOH. Titration is often used to perform the reaction between the two solutions so that the concentration and volume of each solution are known both before and after the reaction. Standardization or merely standardisation are other names for the reaction.
