Description
Ammonia solution 4 mol/l – 4 N is a ready-to-use volumetric standard solution for analytical chemistry and titration work. It corresponds to the system NH₃ + H₂O, with CAS number 1336-21-6 and EG number 215-647-6. The molar mass is given as 17,03 + aq g/mol, the density is 0,967 g/cm³, and the boiling point is 100 °C. The volumetric standard solution from manufacturer Carl ROTH fits analytical and quality-control environments performing acid–base and related volumetric determinations. Ready-to-use presentation reduces preparation effort and supports reproducible titration results. Plastic packaging is practical for routine bench handling and storage within the laboratory. Users can integrate the solution into established volumetric procedures where a 4 N ammonia standard is specified. Clear concentration labelling aids method documentation and traceable analytical workflows in professional laboratory settings.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about Ammonia solution, 4 mol/l - 4 N volumetric standard solution, 500 ml, plastic
What is this article?
Ammonia solution, 4 mol/l - 4 N volumetric standard solution, 500 ml, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in ICP, AAS & ion standards, inside Analytical standards & reference materials, in Lab chemicals.
An ICP, AAS or ion standard is a solution of a stated element or ion at a stated concentration, with an uncertainty. It is the calibration point of a spectrometer or an electrode. The matrix, often dilute acid, has to match the method. A standard past its expiry is not that concentration.
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.
