Beschreibung
EDTA disodium salt solution ROTI®Star 0,05 mol/l - 0,05 N is a volumetric solution of ethylenediaminetetraacetic acid disodium salt dihydrate (CAS 6381-92-6) with the empirical formula C₁₀H₁₄N₂Na₂O₈ · 2 H₂O. Prepared at 0,05 mol/l (0,05 N), it supplies a defined EDTA concentration for volumetric work that specifies this titre. Molar mass is 372,24 g/mol; density is about 1 g/cm³ and the boiling point is approximately 100 °C. A 500 ml plastic bottle provides a convenient laboratory pack for repeated titrations. As a ROTI®Star volumetric solution from manufacturer Carl ROTH, it is grouped with volumetric standard solutions among analytical chemicals. Typical uses of EDTA disodium salt include complexometric titration of metal ions, water-hardness assays and related quantitative methods that depend on a chelating reagent of known normality. The empirical formula corresponds to the dihydrate of the disodium salt, which identifies the dissolved species. Density and boiling-point data support handling of this aqueous volumetric reagent, and the 500 ml plastic presentation is appropriate for routine analytical consumption at 0,05 mol/l.
