Ethylenediaminetetraacetic acid (EDTA) is an aminopolycarboxylic acid widely used as a powerful chelating agent. It binds metal ions through multiple coordination sites, forming highly stable complexes with metals such as iron (Fe), zinc (Zn), manganese (Mn), copper (Cu), calcium (Ca), and magnesium (Mg). Chemical Formula: C₁₀H₁₆N₂O₈ CAS No.: 60-00-4 Molecular Weight: 292.24 g/mol EDTA is typically supplied as a white crystalline solid, while its sodium salts and metal-chelat
