Description
Potassium permanganate solution 0,2 mol/l - 1 N is a volumetric standard solution for quantitative analytical work. Identified by CAS number 7722-64-7 and EG nr. 231-760-3, it provides a defined oxidising titre for redox titrations and related determinations. The solution has a density of 1,019 g/cm³ and a boiling point of approximately 100 °C, and is supplied in a 1 l glass bottle suitable for accurate dispensing. Typical uses include standardisation procedures, determination of oxidisable species and teaching or routine quality-control titrations that rely on permanganate chemistry. This volumetric reagent from manufacturer Carl ROTH is prepared as a ready-to-use 0,2 mol/l (1 N) solution, reducing the need for in-house dilution of solid potassium permanganate. Glass packaging supports chemical compatibility during storage and repeated opening. Analytical laboratories can incorporate the solution directly into established volumetric methods where a stable KMnO₄ titre at this concentration is required, supporting reproducible end-point detection and consistent assay performance across series of measurements.
This article is part of Volumetric standard solutions (titration), in Analytical standards & reference materials.

Questions about Potassium permanganate solution, 0.2 mol/l - 1 N volumetric solution, 1 l, glass
What is this article?
Potassium permanganate solution, 0.2 mol/l - 1 N volumetric solution, 1 l, glass 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.
