Reagecon's EDTA (DiSodium Salt) 0.002M (0.004N) Analytical Volumetric Solution (AVL) is a fully factorised, high purity, stable product, developed and tested for complexometric titrations. This Analytical Volumetric Solution, also called titrant, standard titrant or standard solution,is tested to a specification of ± 0.1%. It is a reagent of known concentration, that is dispensed from a burette or other dispensing apparatus to a sample (analyte), until a reaction between the two liquids is judged to be complete. The product may be used for manual titrations, or more commonly automatic titrations, to determine the end points by detection of any of several properties. Complexometric titrimetry is based on the reaction of a metal ion with a ligand to form a complex. Methods have been developed, validated and published for detection or quantification of almost every metal in the periodic table using EDTA complexation. - Titration is a rapid, economical and versatile analytical tool. This Reagecon AVL is accurate, stable, reproducible and fully factorised. Titrations performed with this product, exhibit defined stoichiometry, are quantitative, establish an equilibrium that is definitive and fast and provide unambiguous results. Stability is proven (either opened or unopened) for the shelf life of this product.
