Description
Potassium hydroxide solution in ethanol 0,05 mol/l (0,05 N) is a volumetric standard solution prepared for analytical titration work in non-aqueous or ethanolic media. The reagent is based on KOH (molar mass 56,11 g/mol) and is characterised by a density of 0,796 g/cm³, a flash point of 12 °C and a boiling point of approximately 78 °C. It is identified by CAS number 1310-58-3 and EG nr. 215-181-3 and is supplied as a 1 l pack for laboratory use. This ethanolic potassium hydroxide volumetric solution is suited to saponification value determinations, acid number titrations and other classical methods that require a defined alkaline titre in alcohol. Clear concentration labelling at 0,05 mol/l / 0,05 N supports reproducible standardisation and endpoint control. The product comes from manufacturer Carl ROTH in the volumetric standard solutions portfolio and is intended for trained laboratory personnel handling flammable alkaline reagents under appropriate safety measures.
This article is part of Volumetric standard solutions (titration), in Analytical standards & reference materials.

Questions about Potassium hydroxide solution in ethanol, 0,05 mol/l, 0,05 N volumetric solution
What is this article?
Potassium hydroxide solution in ethanol, 0,05 mol/l, 0,05 N volumetric solution 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.
