Description
Wijs solution is a volumetric standard reagent prepared at 0,1 mol ICl/l (0,2 N) for analytical iodine-value and related titration work. Supplied in a 1 l glass bottle, it offers a defined iodine monochloride concentration suited to routine volumetric procedures in quality-control and research laboratories. Physical data include a density of 1,062 g/cm³, a flash point of 40 °C and a boiling point of 118 °C, supporting safe handling and process planning. The preparation carries EG nr. 200-580-7 and UN number 2789, reflecting its classification for transport and laboratory use. This Wijs solution from manufacturer Carl ROTH is intended for laboratories that require a ready-to-use ICl volumetric standard without further dilution steps. It fits analytical workflows in food, oil and fat characterisation as well as general volumetric standard applications where a stable 0,2 N iodine monochloride titre is specified. Clear labelling of concentration and pack format helps maintain traceability from receipt through to day-to-day titration practice.

Questions about Wijs-solution, 0,1 mol ICl/l - 0,2 N, 1 l, glass
What is this article?
Wijs-solution, 0,1 mol ICl/l - 0,2 N, 1 l, glass 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.
