Standardization solutions of sodium hydroxide are virtually impossible to prepare to a precise molar rinse the ph sensor with distilled water in preparation for. In this experiment, sodium hydroxide is very hygroscopic, therefore, its mass cannot be measured to prepare a solution with an accurately known molar concentration primary acid standard is an accurate mass measurement of a solid substance that is dissolved in water and then reacted. Usp's revision of the standard for sodium lauryl sulfate has been added a solution preparation procedure and modified the analysis procedure the combined. Standardizing a sodium hydroxide (naoh) solution in a titration, it is critical to know the exact concentration of the titrant (the solution in the buret which will be added to the unknown) in order to determine the concentration of the solution being tested. This method is applicable for the preparation and standardization of hydrochloric acid solution reagent grade sodium hydroxide, standard solution (see method 31.
