Description
Oxalic acid solution 0,25 mol/l – 0,5 N is a ready-prepared volumetric reagent for analytical titration and quantitative laboratory assays. Listed under CAS number 6153-56-6, it is supplied at a defined concentration of 0,25 mol/l (0,5 N) for standardised redox and acidimetric work. The aqueous solution shows a density of 1,008 g/cm³ and a boiling point of 100 °C, consistent with dilute oxalic acid preparations used on the analytical bench. Packaging is 1 l in a plastic bottle, a convenient unit for routine volumetric procedures in quality-control, research and teaching environments. This oxalic acid volumetric solution from manufacturer Carl ROTH supports protocols that specify a 0,5 N titre without on-site standardisation from solid reagent. The EG number is 205-634-3. Typical laboratory contexts include titration workflows and preparation of reference titres where oxalic acid is the preferred primary or working standard. Observe ordinary chemical hygiene and consult the safety documentation before use.
This article is part of Volumetric standard solutions (titration), in Analytical standards & reference materials.

Questions about Oxalic acid solution, 0,25 mol/l - 0,5 N volumetric solution, 1 l, plastic
What is this article?
Oxalic acid solution, 0,25 mol/l - 0,5 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.
