Sodium hydroxide solution, 0,33 mol/l – 0,33 N, volumetric standard solution
A volumetric standard solution is a solution containing a precisely known concentration of a substance. The concentration of a volumetric standard solution is determined using a primary standard, which is accurately weighed and dissolved to make a specific volume. Volumetric standard solutions are made using reagent-grade (p.a.) substances as source materials.
The advantages of this over making them yourself are:
