Description
EDTA disodium salt volumetric standard is a ready-to-use titration solution at 0,1 mol/l (0,1 N), conforming to Reag. Ph.Eur. requirements for volumetric analysis. The reagent corresponds to CAS number 6381-92-6, with empirical formula C₁₀H₁₄N₂Na₂O₈ · 2 H₂O and a molar mass of 372,24 g/mol. Density is 1,03 g/cm³ and the boiling point is approximately 100 °C. Supplied in a 1 l pack, this standard solution from manufacturer Carl ROTH is intended for precise complexometric titrations and related measuring methods in environmental analysis and general laboratory titration work. Consistent concentration and pharmacopoeia-aligned quality support reliable endpoint determination and routine analytical procedures where EDTA-based complexation is required.
This article is part of Volumetric standard solutions (titration), in Analytical standards & reference materials.

Questions about EDTA disodium salt volumetric standard, solut. 0,1 mol/l - 0,1 N, Reag. Ph.Eur.
What is this article?
EDTA disodium salt volumetric standard, solut. 0,1 mol/l - 0,1 N, Reag. Ph.Eur. 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.
