Description
Sodium hydroxide solution 0,4 mol/l - 0,4 N is a volumetric standard solution for analytical titration and quantitative laboratory applications. The reagent carries CAS number 1310-73-2 and EG number 215-185-5, with empirical formula NaOH and a molar mass of 40,01 g/mol. Measured physical data include a density of 1,016 g/cm³ and a boiling point of 100 °C. It is packed as 1 l in plastic, providing a practical volume for routine volumetric work at the stated 0,4 mol/l (0,4 N) concentration. Analytical chemistry laboratories employ such sodium hydroxide volumetric standard solutions for acid–base titrations, titre adjustments, and related wet-chemical procedures that require a defined normality. This solution is offered from manufacturer Carl ROTH for use on titration benches and in method-controlled analytical sequences. Clear identification by CAS, EG, concentration, and density supports documentation, inventory control, and hazard communication. Use in accordance with validated analytical methods and laboratory safety practice for alkaline solutions; UN number 1824 applies for transport classification.
This article is part of Volumetric standard solutions (titration), in Analytical standards & reference materials.

Questions about Sodium hydroxide solution, 0,4 mol/l - 0,4 N volumetric solution, 1 l, plastic
What is this article?
Sodium hydroxide solution, 0,4 mol/l - 0,4 N volumetric solution, 1 l, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Volumetric standard solutions (titration), inside Analytical standards & reference materials, in Lab chemicals.
A volumetric standard solution is a reagent of stated concentration for titration, such as a stated molarity of acid, base or silver nitrate. The factor or the exact titre is on the certificate. Using the nominal molarity when a factor is printed is a systematic error.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
