Description
Ammonium sulphate solution is a ready-to-use volumetric standard at 0,1 mol/l (0,1 M) for quantitative analytical work. With CAS number 7783-20-2, empirical formula (NH₄)₂SO₄ and molar mass 132,14 g/mol, it provides a defined sulphate source for titrations and calibration. Density is approximately 1 g/cm³ and the boiling point is 100 °C. Supplied as a 1 l plastic pack, the solution is intended for routine volumetric procedures in analytical and quality-control laboratories. This preparation from manufacturer Carl ROTH supports reproducible end-point determinations and standardisation workflows where a stable ammonium sulphate titre is required. Typical uses include preparation of reference media, precipitation and gravimetric checks, and general wet-chemistry assays that call for a known sulphate concentration. The clear aqueous format simplifies handling and dilution steps while maintaining the stated molarity for consistent laboratory performance across repeated analytical runs.
This article is part of Volumetric standard solutions (titration), in Analytical standards & reference materials.

Questions about Ammonium sulphate solution, 0,1 mol/l - 0,1 M, volumetric solution, 1 l, plastic
What is this article?
Ammonium sulphate solution, 0,1 mol/l - 0,1 M, 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.
