Description
Potassium hydroxide solution 7 mol/l – 7 N is a ready-to-use volumetric standard solution with the empirical formula KOH and CAS number 1310-58-3. The preparation shows a molar mass of 56,11 g/mol, a density of 1,29 g/cm³ and a boiling point above 100 °C, making it appropriate for accurate acid–base titrations and related analytical procedures. Delivered in a 1 l plastic bottle, it provides laboratories with a defined 7 N normality while avoiding the variability of in-house preparation from solid potassium hydroxide. Typical applications cover standardisation of acids, determination of acidity in process samples and routine quality-control assays in chemical, environmental and pharmaceutical laboratories. This volumetric solution from manufacturer Carl ROTH is part of a broader range of analytical chemicals intended for reproducible laboratory work. The ready-to-use format shortens preparation time and helps keep titres consistent across operators and instruments. The clear aqueous alkali integrates smoothly into manual and automated titration protocols that require a stable potassium hydroxide concentration.
This article is part of Volumetric standard solutions (titration), in Analytical standards & reference materials.

Questions about Potassium hydroxide solution, 7 mol/l - 7 N volumetric solution, 1 l, plastic
What is this article?
Potassium hydroxide solution, 7 mol/l - 7 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.
