Description
EDTA disodium salt solution ROTI®Star 0,01 mol/l - 0,01 N is a volumetric solution of ethylenediaminetetraacetic acid disodium salt dihydrate (CAS 6381-92-6) with the empirical formula C₁₀H₁₄N₂Na₂O₈ · 2 H₂O. The stated concentration of 0,01 mol/l (0,01 N) provides a defined EDTA titre for laboratory volumetric analysis. Molar mass is 372,24 g/mol, density is approximately 1 g/cm³ and the boiling point is 100 °C, in line with an aqueous volumetric reagent. The article is supplied as a 500 ml fill in a plastic bottle, a practical pack size for routine titration work. This ROTI®Star volumetric solution from manufacturer Carl ROTH belongs to the analytical chemicals used as volumetric standard solutions. EDTA disodium salt solutions are employed in complexometric titration of metal cations, determination of water hardness and other quantitative procedures that rely on a chelating titrant of known molarity. Physical properties such as density and boiling point assist handling and documentation in the analytical laboratory, while the plastic 500 ml presentation is suited to aqueous volumetric reagents of this concentration.
