Description
Sodium hydroxide solution 0,2 mol/l – 0,2 N is a ready-to-use volumetric standard solution for reliable acid–base titration in the analytical laboratory. With CAS number 1310-73-2 and empirical formula NaOH, it delivers a clearly defined base concentration for quantitative work. The molar mass is 40,01 g/mol, density is 1 g/cm³, and the boiling point is 100 °C. This volumetric reagent from manufacturer Carl ROTH is suited to standardisation of acids, assay of acidic samples, and general titration protocols that call for 0,2 N sodium hydroxide. Chemical, pharmaceutical, and environmental laboratories can apply it where a medium-strength alkaline titre is required. Consistent labelling of concentration and physical properties supports traceable results and efficient integration into existing SOPs.
This article is part of Volumetric standard solutions (titration), in Analytical standards & reference materials.

Questions about Sodium hydroxide solution, 0,2 mol/l - 0,2 N volumetric solution, 1 l, plastic
What is this article?
Sodium hydroxide solution, 0,2 mol/l - 0,2 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.
