Description
Sulphuric acid approx. 2 mol/l – approx. 4 N is a silicate-free volumetric solution intended for analytical titration and related quantitative procedures. It is characterised by CAS number 7664-93-9 and empirical formula H₂SO₄, with a molar mass of 98,08 g/mol and a density of 1,121 g/cm³. The approximate concentration of 2 mol/l (about 4 N) makes the reagent suitable where a stronger sulphuric acid titrant is required without silicate interference. Offered in a 1 l plastic bottle from manufacturer Carl ROTH, the solution carries EG number 231-639-5 and UN number 2796. Laboratories select silicate-free volumetric sulphuric acid for methods sensitive to silicate contamination, including selected standardisations and industrial or environmental assays. The ready-to-use presentation supports consistent preparation of analytical workflows and reduces handling steps compared with diluting concentrated acid in-house when the stated strength fits the method.
This article is part of Volumetric standard solutions (titration), in Analytical standards & reference materials.

Questions about Sulphuric acid approx. 2 mol/l – approx. 4 N volumetric solution, silicate-free, 1 l
What is this article?
Sulphuric acid approx. 2 mol/l – approx. 4 N volumetric solution, silicate-free, 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.
