Description
Hydrochloric acid 3 mol/l – 3 N is a ready-to-use volumetric solution for analytical titration and quantitative laboratory work. With the empirical formula HCl, CAS number 7647-01-0 and a molar mass of 36,46 g/mol, it delivers a defined acid strength of 3 mol/l (3 N) for standardised acid–base procedures. The solution has a density of 1,049 g/cm³ and a boiling point of 85 °C, supporting consistent handling under typical bench conditions. Supplied as a 1 l fill in a plastic bottle, the pack size suits routine volumetric analysis in quality-control, teaching and research laboratories. This hydrochloric acid volumetric standard from manufacturer Carl ROTH is intended wherever a stable, accurately prepared 3 N titre is required. The EG number is 231-595-7. Classical wet-chemical assays, standardisation of bases and preparation of reference titres commonly use this concentration. Appropriate personal protective equipment and fume-hood practice remain essential when working with hydrochloric acid solutions of this strength.
This article is part of Volumetric standard solutions (titration), in Analytical standards & reference materials.

Questions about Hydrochloric acid, 3 mol/l - 3 N volumetric solution, 1 l, plastic
What is this article?
Hydrochloric acid, 3 mol/l - 3 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.
