Description
Potassium hydroxide solution 0,5 mol/l - 0,5 N volumetric solution is a standardised alkaline reagent with the empirical formula KOH, CAS number 1310-58-3, and molar mass 56,11 g/mol. Supplied at 0,5 mol/l (0,5 N), it is designed for volumetric analysis, acid–base titrations, and other quantitative laboratory procedures that require a defined hydroxide normality. Reported physical properties include a density of approximately 1,028 g/cm³ and a boiling point of about 100 °C. The EG number is 215-181-3 and the UN number is 1814. From manufacturer Carl ROTH, the product belongs to the volumetric standard solutions portfolio used in analytical chemistry and quality-control environments. Consistent concentration labelling supports method validation, routine titration series, and teaching laboratory exercises. Handle as a corrosive alkaline solution with suitable personal protective equipment and compatible labware. The ready-made 0,5 N format reduces on-site standardisation effort while maintaining the precision expected of volumetric KOH reagents in everyday wet-chemical workflows.
This article is part of Volumetric standard solutions (titration), in Analytical standards & reference materials.

Questions about Potassium hydroxide solution, 0.5 mol/l - 0.5 N volumetric solution, 1 l
What is this article?
Potassium hydroxide solution, 0.5 mol/l - 0.5 N volumetric solution, 1 l 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.
