Description
EDTA disodium salt solution is a 0,2 mol/l - 0,2 N volumetric solution prepared for analytical titration and complexometric work. The solute corresponds to the dihydrate form with empirical formula C₁₀H₁₄N₂Na₂O₈ · 2 H₂O, molar mass 372,24 g/mol, density 1,039 g/cm³ and boiling point around 100 °C. Identity is given by CAS number 6381-92-6 and EG number 205-358-3. Concentration and physical data from manufacturer Carl ROTH help match the reagent to established volumetric methods without intermediate dilution steps when the stated normality is required. The solution is positioned among analytical volumetric standard solutions for quantitative work.
This article is part of Volumetric standard solutions (titration), in Analytical standards & reference materials.

Questions about EDTA disodium salt solution, 0,2 mol/l - 0,2 N volumetric solution, 1 l, plastic
What is this article?
EDTA disodium salt solution, 0,2 mol/l - 0,2 N volumetric solution, 1 l, plastic 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.
