Description
Sulphuric acid 0,125 mol/l - 0,25 N is a dilute volumetric standard solution for fine-scale titrimetric analysis. Bearing CAS number 7664-93-9 and empirical formula H₂SO₄, it is specified at 0,125 mol/l (0,25 N), with molar mass 98,08 g/mol, density 1,006 g/cm³ and boiling point 100 °C. Delivered in a 1 l plastic bottle, the solution is convenient for direct use in methods that require a low-normality acid titrant. Produced by Carl ROTH, it supports accurate standardisation and gentle acidimetric determinations without the need for extensive pre-dilution. Typical laboratory uses include titration of dilute bases, educational volumetric exercises and quality-control assays where a mild sulphuric acid concentration improves end-point control. The combination of defined concentration, known density and full chemical identifiers (CAS, EG nr.) aids method transfer, documentation and batch-to-batch consistency in analytical and teaching laboratories handling volumetric standard solutions.
This article is part of Volumetric standard solutions (titration), in Analytical standards & reference materials.

Questions about Sulphuric acid, 0,125 mol/l - 0,25 N volumetric solution, 1 l, plastic
What is this article?
Sulphuric acid, 0,125 mol/l - 0,25 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.
