Description
EDTA disodium salt solution is a 0,5 mol/l - 0,5 N volumetric solution prepared for analytical titration and complexometric work. The reagent corresponds to CAS number 6381-92-6, empirical formula C₁₀H₁₄N₂Na₂O₈ · 2 H₂O, molar mass 372,24 g/mol, density 1,106 g/cm³, and boiling point 100 °C, with EG nr. 205-358-3. Supplied in a 1 l pack, it is ready for use as a standardised volumetric solution in quantitative laboratory procedures. Physical data support straightforward handling and method setup in analytical chemistry workflows. This EDTA disodium salt solution from manufacturer Carl ROTH is intended for volumetric standard applications where a defined 0,5 mol/l - 0,5 N titre is required. The dihydrate salt basis and stated concentration help ensure consistent complex formation with divalent metal ions during titration. Laboratories can integrate the 1 l unit into routine quality control, teaching, or research protocols that rely on EDTA-based volumetric analysis. Clear labelling of concentration, CAS identity, and key physicochemical values supports traceable use in the analytical suite.

Questions about EDTA disodium salt solution , 0,5 mol/l - 0,5 N volumetric solution, 1 l
What is this article?
EDTA disodium salt solution , 0,5 mol/l - 0,5 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 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.
