EDTA Disodium Salt 25kg Bag

EDTA disodium Salt is ethylendiaminetetraacetic acid (EDTA-H₂Na₂).  Ethylendiaminetetraacetic acid C₁₀N₁₆N₂O₈, is an aminocarboxylic acid with 6 functional groups.

EDTA disodium salt is a water-soluble, white crystalline powder that acts as a chelating agent, meaning it bind to metal ions,

effectively removing them from a solution or preventing them from participating in other chemical reactions.

The most important property of EDTA Disodium Salt is it’s ability to form water-soluble complexes with polyvalent ions (e.g. calcium, magnesium, lead, copper, zinc, cadmium, mercury, manganese, iron and aluminium) over a wide pH range from 2 to 13.5.

EDTA usually forms 1:1 complexes i.e. 1 mol of EDTA chelates binds to 1 mol of metal ions.  The metal ion is completely enclosed by the ligand.

These complexes remain stable, especially in alkali media and even at temperatures of up to 100^oc.

EDTA disodium Salt has superior chemical stability and is highly stable with other organic chelating agents (e.g. citric acid, tartaric acid and gluconate) especially at high temperatures.

Unlike inorganic chelating agents (e.g. triphosphate), hydrolysis does not occur for longer periods of time, even when applying pressure at 200^oc.  The water however, evaporates at high temperatures.
