Description
EDTA disodium solution ROTI®Volum is a 0,1 mol/l (0,1 N) volumetric standard solution supplied in ampoule form for complexometric titration and quantitative metal analysis. Identified by CAS number 6381-92-6 and EG nr. 205-358-3, the reagent has the empirical formula C₁₀H₁₄N₂Na₂O₈ · 2 H₂O and a molar mass of 372,24 g/mol. Density is given as 1,03 g/cm³ with a boiling point of 100 °C, values that support reliable dilution and handling in aqueous titration media. The unit is packed as 1 pc at 0,251 kg, providing a practical concentrate for preparing working EDTA solutions in analytical and quality-control laboratories. This ROTI®Volum grade from manufacturer Carl ROTH is intended for applications such as determination of water hardness, chelatometric end-point titrations, and standardisation of metal-ion methods. Ampoule delivery helps maintain defined concentration until the moment of use and simplifies inventory for both routine and specialised analytical chemistry environments.
This article belongs on Volumetric standard solutions (titration), in Analytical standards & reference materials.

Questions about EDTA disodium solution, ROTI®Volum 0,1 mol/l - 0,1 N, ampoule, 1 unit(s)
What is this article?
EDTA disodium solution, ROTI®Volum 0,1 mol/l - 0,1 N, ampoule, 1 unit(s) 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 Produits chimiques de laboratoire et industriels.
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.
