Description
Potassium hydroxide solution is a 2,5 mol/l (2,5 N) volumetric standard solution formulated for precise titration and analytical standardisation. With empirical formula KOH, CAS number 1310-58-3 and molar mass 56,11 g/mol, it supplies a defined alkaline concentration for quantitative laboratory use. Density is 1,115 g/cm³ and the boiling point is 100 °C. The product is offered in a 1 l pack, suitable for routine volumetric applications in analytical chemistry and quality-control environments. Available from manufacturer Carl ROTH within the volumetric standard solutions range, it supports acid–base titrations, standardisation steps and related procedures that call for a 2,5 N potassium hydroxide titre. EG number 215-181-3 refers to the potassium hydroxide component. Handle as a corrosive alkaline reagent with appropriate protective measures and laboratory good practice. This ready-to-use solution is a practical choice whenever a higher-strength, accurately specified KOH volumetric standard in litre format is needed.
This article is part of Volumetric standard solutions (titration), in Analytical standards & reference materials.

Questions about Potassium hydroxide solution, 2,5 mol/l - 2,5 N volumetric solution, 1 l
What is this article?
Potassium hydroxide solution, 2,5 mol/l - 2,5 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.
