Description
EDTA disodium salt solution A 0,1 mol/l – 0,1 N is a volumetric standard solution formulated for complexometric titration and water-hardness determination. It carries CAS number 6381-92-6 and the empirical formula C₁₀H₁₄N₂Na₂O₈ · 2 H₂O, with a molar mass of 372,24 g/mol, a density of 1,038 g/cm³ and a boiling point of 100 °C. The 0,1 N concentration is suited to chelatometric assays, metal-ion titration and physical-property measurements linked to water hardness. Supplied in a 1 l pack, the ready-to-use solution supports direct application in analytical workflows without intermediate dilution. This EDTA disodium salt volumetric reagent from manufacturer Carl ROTH is used where a defined complexing titre is required for reproducible endpoint detection. Laboratories engaged in water analysis and related titrimetric methods benefit from the specified molarity and physical data. Consistent concentration supports reliable quantitative results in routine hardness and complexometric determinations.
This article belongs on Volumetric standard solutions (titration), in Analytical standards & reference materials.

Questions about EDTA disodium salt solution A, 0.1 mol/l - 0.1 N volumetric solution, 1 l
What is this article?
EDTA disodium salt solution A, 0.1 mol/l - 0.1 N volumetric solution, 1 l 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.
