Description
Potassium hydroxide solution 0,25 mol/l − 0,25 N is a ready-to-use volumetric standard solution for precise acid–base titration and analytical laboratory applications. With CAS number 1310-58-3, empirical formula KOH and molar mass 56,11 g/mol, it delivers a defined 0,25 N alkali concentration for quality control, method development and routine assays. Reported physical properties include a density of 1,014 g/cm³ and a boiling point of approximately 100 °C. Packed as 1 l, the solution is convenient for workflows that require a stronger standardized KOH titre than dilute grades. Consistent concentration supports reproducible end-point detection and calibration of volumetric methods. This product from manufacturer Carl ROTH forms part of the volumetric standard solutions portfolio and carries EG number 215-181-3; transport classification uses UN number 1814. It is intended for laboratories seeking a reliable potassium hydroxide volumetric reagent without preparing stock solutions from solid material.
This article is part of Volumetric standard solutions (titration), in Analytical standards & reference materials.

Questions about Potassium hydroxide solution, 0.25 mol/l - 0.25 N volumetric solution, 1 l
What is this article?
Potassium hydroxide solution, 0.25 mol/l - 0.25 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.
