Description
EDTA disodium salt solution ROTI®Star 0,01 mol/l - 0,01 N is a volumetric solution of ethylenediaminetetraacetic acid disodium salt dihydrate (CAS 6381-92-6) with the empirical formula C₁₀H₁₄N₂Na₂O₈ · 2 H₂O. The stated concentration of 0,01 mol/l (0,01 N) provides a defined EDTA titre for laboratory volumetric analysis. Molar mass is 372,24 g/mol, density is approximately 1 g/cm³ and the boiling point is 100 °C, in line with an aqueous volumetric reagent. The article is supplied as a 500 ml fill in a plastic bottle, a practical pack size for routine titration work. This ROTI®Star volumetric solution from manufacturer Carl ROTH belongs to the analytical chemicals used as volumetric standard solutions. EDTA disodium salt solutions are employed in complexometric titration of metal cations, determination of water hardness and other quantitative procedures that rely on a chelating titrant of known molarity. Physical properties such as density and boiling point assist handling and documentation in the analytical laboratory, while the plastic 500 ml presentation is suited to aqueous volumetric reagents of this concentration.

Questions about EDTA disodium salt solution ROTI®Star 0,01 mol/l - 0,01 N, 500 ml, plastic
What is this article?
EDTA disodium salt solution ROTI®Star 0,01 mol/l - 0,01 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.
