determined by colorimetric titration‚ and the identity of an unknown acid was determined by potentiometric titration. In the first titration‚ a strong acid standard‚ potassium hydrogen phthalate (KHP)‚ was used‚ to determine the concentration of a strong base‚ sodium hydroxide (NaOH). In order to do so‚ we prepared NaOH solution‚ prepared a buret‚ and standardized this solution by performing a colorimetric titration of the KHP with the solution until a color change was present. The color change was introduced
