Primary standards are those chemical reagents having high percent purity, about 99%, stable towards the air, have high molecular mass, readily soluble in the solvent as well as readily available. A standard solution is a solution in which its concentration is accurately known. The standard solution that reacts with the substance is being analyzed. Primary standard and standard solution are typically used in titration to determine an unknown concentration. During the standardization of NaOH solution, potassium hydrogen phthalate, KHC8H4O4 acts as the primary acid standard which determines the molar concentration of a sodium hydroxide. After standardizing the NaOH solution, it is called a secondary standard solution. Titration is a common laboratory method of quantitative chemical analysis that is used to determine the unknown concentration of an identified analyte (Medwick & Kirschner, 2010). In this experiment, a buret is used to dispense a the standardized NaOH solution (titrant) into a flask containing the acid solution (analyte). An indicator is used to signal the stoichiometric point during the titration. The phenolphthalein indicator is used whereby it is colorless when it is added into the acid solution and it turns into pink as soon as the solution is basic, as soon as the pink solution is formed, the titration
