Beschreibung
Potassium permanganate (KMnO₄, CAS 7722-64-7) is an inorganic analytical salt offered at a minimum purity of 99 % in p.a., ACS grade. Its empirical formula is KMnO₄, with a molar mass of 158,04 g/mol and a density of 2,7 g/cm³, supporting precise preparation of standard solutions and controlled oxidation work in the laboratory. The EG number is 231-760-3. This grade is intended for salts for analysis (p.a.) and related inorganic chemical applications where defined purity and reproducible behaviour are required. The product is Potassium permanganate from manufacturer Carl ROTH provides a clearly specified reagent identity for titration, sample preparation, and general analytical procedures. Physical data such as molar mass and density facilitate accurate weighing and solution make-up, while the p.a., ACS designation aligns the material with common laboratory specifications for high-purity inorganic salts used across research, teaching, and industrial analytical environments.
This article belongs on Volumetric standard solutions (titration), in Analytical standards & reference materials.

Questions about Potassium permanganate, min. 99 %, p.a., ACS, 500 g, plastic
What is this article?
Potassium permanganate, min. 99 %, p.a., ACS, 500 g, 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 Labor- und Industriechemikalien.
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.
