Description
Sulphuric acid 6 mol/l – 12 N is a concentrated volumetric standard solution for demanding analytical titrations. Identified by CAS number 7664-93-9 and empirical formula H₂SO₄, it has a molar mass of 98,08 g/mol and a density of 1,339 g/cm³. The high defined strength of 6 mol/l (12 N) is suited to procedures that call for a strong sulphuric acid titrant or stock volumetric reagent. Packed in a 1 l plastic bottle from manufacturer Carl ROTH, the product is listed under EG number 231-639-5 and UN number 2796. Chemical and analytical laboratories employ such volumetric sulphuric acid solutions for acid–base work, sample preparation steps and quantitative assays where a reproducible high normality is specified. The ready-prepared format helps maintain method consistency and limits the need for on-site dilution of concentrated acid when the stated concentration matches the analytical protocol.
This article is part of Volumetric standard solutions (titration), in Analytical standards & reference materials.

Questions about Sulphuric acid 6 mol/l – 12 N volumetric solution, 1 l
What is this article?
Sulphuric acid 6 mol/l – 12 N volumetric solution, 1 l 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.
