Description
Nitric acid ROTI®Star 4 mol/l - 4 N is a volumetric solution of nitric acid (CAS 7697-37-2) with the empirical formula HNO₃ and a molar mass of 63,01 g/mol. The 4 N titre is supplied in a 500 ml plastic bottle for analytical work that calls for a defined nitric acid concentration. Physical properties include a density of 1,128 g/cm³ and a boiling point above 83 °C. Regulatory identifiers are UN number 2031 and EG number 231-714-2. This ROTI®Star volumetric solution from manufacturer Carl ROTH is used in titrations, reagent standardisation and other wet-chemical procedures that specify 4 mol/l nitric acid. The 500 ml plastic pack supports routine laboratory handling of the aqueous acid. Analysts can record molarity, molar mass, density and boiling point in method and inventory documentation. As a prepared volumetric solution, the product is intended for analytical chemistry rather than as a bulk concentrated acid. Matching the 4 mol/l (4 N) concentration and HNO₃ identity to the method helps laboratories select the correct nitric acid reagent for volumetric applications.

Questions about Nitric acid ROTI®Star 4 mol/l - 4 N, 500 ml, plastic
What is this article?
Nitric acid ROTI®Star 4 mol/l - 4 N, 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.
Which category should I open next?
The category is Analytical standards & reference materials. The sub-category is ICP, AAS & ion standards. The catalogue is Lab chemicals.
Shelves beside this one are Chromatography standards (GC, HPLC, pesticides), Reference substances & reagents (other), Volumetric standard solutions (titration), Reagents for analysis (Ph. Eur., ASTM, DIN), Spectroscopy & physical property standards and Indicators & indicator solutions.
What should I check before I order?
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
