Description
Sulphuric acid ROTI®Star 2,5 mol/l - 5 N is a volumetric solution of sulphuric acid with empirical formula H₂SO₄, CAS number 7664-93-9 and molar mass 98,08 g/mol. Density is 1,15 g/cm³. This 2,5 mol/l (5 N) preparation comes in a 500 ml plastic pack and is intended for volumetric analysis in the analytical laboratory. EG number 231-639-5 and UN number 2796 identify the mineral acid for classification and transport. Volumetric sulphuric acid solutions are used for acid–base titrations, titre determination and wet-chemical procedures that require a defined normality. The ROTI®Star volumetric solution from manufacturer Carl ROTH belongs to the volumetric standard solutions used in analytical chemistry. The 500 ml plastic container supports routine bench work with a practical working volume. Stated molarity, 5 N normality and density 1,15 g/cm³ help analysts plan dilutions and calculate consumption during titration sequences. Pack weight is 0,700 kg. Sulphuric acid is a fundamental reagent whenever a strong diprotic acid of known concentration is required in quantitative inorganic and analytical chemistry.

Questions about Sulphuric acid, ROTI®Star 2,5 mol/l - 5 N, 500 ml, plastic
What is this article?
Sulphuric acid, ROTI®Star 2,5 mol/l - 5 N, 500 ml, 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.
