The packing material is kraft paper established bag with the 25kg insode lining palstic bag
it is a polyamino carboxylic acid and a colourless, water-soluble solid. Its conjugate base is named ethylenediaminetetraacetate. It is widely
used to dissolve limescale. Its usefulness
arises because of its role as a hexadentate ("six-toothed") ligand and chelating agent, i.e. its ability to "sequester" metal ions such
as Ca2+ and Fe3+. After being bound by EDTA, metal ions remain in solution but
exhibit diminished reactivity. EDTA is produced as several salts, notably disodium
EDTA and calcium disodium EDTA.
