Description
Potassium hydroxide solution is a 2 mol/l (2 N) volumetric standard solution for reliable acid–base titration and analytical standardisation. It is based on empirical formula KOH, CAS number 1310-58-3 and molar mass 56,11 g/mol, giving a clearly defined alkaline titre. Density is 1,092 g/cm³ and the boiling point is 100 °C. Supplied in a 1 l plastic pack, the solution is practical for everyday volumetric work in analytical and quality-control laboratories. This preparation from manufacturer Carl ROTH belongs to the volumetric standard solutions portfolio and is suited to titrations, reagent preparation and calibration procedures that specify a 2 N potassium hydroxide titre. EG number 215-181-3 identifies the potassium hydroxide component. As a corrosive alkaline solution, it should be handled with suitable personal protective equipment and standard laboratory controls. Choose this ready-to-use volumetric KOH solution when a stable 2 mol/l concentration in a convenient plastic litre pack is required.
This article is part of Volumetric standard solutions (titration), in Analytical standards & reference materials.

Questions about Potassium hydroxide solution, 2 mol/l - 2 N volumetric solution, 1 l, plastic
What is this article?
Potassium hydroxide solution, 2 mol/l - 2 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.
