Description
Sodium hydroxide solution 8 mol/l - 8 N is a concentrated volumetric standard solution prepared for quantitative laboratory analysis. With CAS number 1310-73-2 and empirical formula NaOH, it delivers a defined eight-normal strength suited to titrations, stock-base preparation and analytical methods that call for a stronger sodium hydroxide volumetric reagent. Physical data include a molar mass of 40,01 g/mol, a density of 1,27 g/cm³ and a boiling point of 100 °C, which inform handling and dispensing practice. The solution is supplied in a 1 l plastic pack for convenient use on analytical and quality-control benches. This volumetric solution from manufacturer Carl ROTH supports acid–base titrations, standardisation work and dilution to lower working concentrations where an 8 mol/l starting base is preferred. EG number 215-185-5 provides the European inventory reference for the substance. Laboratories engaged in classical wet chemistry, process control or teaching environments can apply this ready volumetric grade whenever protocols specify an 8 N sodium hydroxide solution in plastic packaging.
This article is part of Volumetric standard solutions (titration), in Analytical standards & reference materials.

Questions about Sodium hydroxide solution, 8 mol/l - 8 N volumetric solution, 1 l, plastic
What is this article?
Sodium hydroxide solution, 8 mol/l - 8 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.
