Why does the molarity of NaOH usually have to be standardized? When preparing the aqueous NaOH, the exact volume of the NaOH used cannot be measured due to water being hygroscopic. Solid NaOH can react with acid very easily and therefore the initial mass of the base may not be exact. When dissolving the solid NaOH in pure distilled water, the exact volume of the NaOH used cannot be measured due to buret calibration. Solid NaOH can react with water in the air very easily and therefore the initial mass of the base may not be exact.
