The balanced equation for the reaction between KHP and NaOH is KHC8H4O4 + NaOH = NaKC8H4O4 + H2O. The chemical formula for potassium hydrogen phthalate is KHC8H4O4.
When KHP and NaOH combine, a positive hydrogen ion and a negative hydrogen atom are released from KHC8H4O4 and NaOH, respectively. The chemical formula for water is H2O, which is formed when these two atoms mix with the oxygen from the NaOH. Typically, titration is used to perform the reaction between the two solutions, such that the concentration and volume of each solution are known both before and after the reaction. The reaction is often referred to as standard titration or standardisation.
