Potassium sulphate solution is a 0,5 mol/l (0,5 M) volumetric standard solution of potassium sulphate for analytical laboratory use. The reagent corresponds to CAS number 7778-80-5, EG nr. 231-915-5 and empirical formula K₂SO₄, with a molar mass of 174,27 g/mol. Stated physical properties include a density of 1,065 g/cm³ and a boiling point of 100 °C. Supplied in a 500 ml pack, this volumetric solution supports titrimetric and other quantitative procedures that require a defined potassium sulphate concentration. Potassium sulphate solution from manufacturer Carl ROTH is intended for analytical chemistry workflows within volumetric standard solution ranges. The ready concentration simplifies preparation of working standards and calibration steps where K₂SO₄ at 0,5 mol/l is specified. Clear identity data (CAS, EG number and formula) aid method documentation and reagent traceability. Laboratories performing routine volumetric analysis can integrate the 500 ml unit directly into standard operating procedures without intermediate dilution to the nominal 0,5 M level.
This article is part of Volumetric standard solutions (titration), in Analytical standards & reference materials.

Questions about Potassium sulphate solution, 0,5 mol/l volumetric solution, 500 ml
What is this article?
Potassium sulphate solution, 0,5 mol/l volumetric solution, 500 ml 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 Chemicaliën.
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.
