Description
Sodium thiosulphate solution is a 1 mol/l - 1 N volumetric standard solution formulated for analytical titration and iodometric laboratory applications. The product is packed as 1 l in plastic, giving a generous working volume for repeated assays in industrial QC, academic, and research settings. Density is stated in the range 1 to 1,1 g/cm³, and the boiling point is approximately 100 °C. The empirical formula is Na₂O₃S₂, identifying the dissolved thiosulphate species used in classical redox titrations. This volumetric reagent from manufacturer Carl ROTH is ready for direct use, supporting methods that specify a 1 N sodium thiosulphate titre without intermediate preparation from crystalline salt. Categories place it among analytical chemicals and volumetric standard solutions, underlining its role in quantitative wet chemistry. The plastic container facilitates bench handling and storage between series of measurements. Laboratories can apply the solution in standardised burette workflows where consistent normality is essential. Pack weight is 1,220 kg for shipping and inventory purposes. Follow established laboratory procedures when dispensing and titrating with this reagent.
This article is part of Volumetric standard solutions (titration), in Analytical standards & reference materials.

Questions about Sodium thiosulphate solution, 1 mol/l - 1 N volumetric solution, 1 l, plastic
What is this article?
Sodium thiosulphate solution, 1 mol/l - 1 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.
