Description
Sulphuric acid 2,5 mol/l – 5 N is a volumetric standard solution with empirical formula H₂SO₄, CAS number 7664-93-9 and molar mass 98,08 g/mol. This ready-to-use analytical reagent exhibits a density of 1,15 g/cm³ and is formulated for precise titrations and quantitative laboratory determinations. Packaged in a 1 l plastic bottle, the solution delivers defined normality for acid–base standardization, endpoint work and routine volumetric analysis. The product is available from manufacturer Carl ROTH as part of its volumetric standard solutions range. Identified under EG number 231-639-5 and UN number 2796, it supports reproducible results in research, quality control and classical wet-chemistry workflows. Laboratories rely on this 5 N sulphuric acid preparation when a strong acid of known titre is essential for stoichiometric calculations and consistent molarity throughout analytical series.
This article is part of Volumetric standard solutions (titration), in Analytical standards & reference materials.

Questions about Sulphuric acid, 2,5 mol/l - 5 N volumetric solution, 1 l, plastic
What is this article?
Sulphuric acid, 2,5 mol/l - 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.
