Answer:
EDTA is ethylenediamine tetraacetic acid. It is a strong chelating agent. It has many uses including:

2) Detergents: complexation of Ca2+ and Mg2+ (reduction of water hardness)
3) Photography: use of Fe (III) EDTA as oxidizing agent
4) Pulp and paper industry: complexation of heavy metals during chlorine-free bleaching, stabilization of hydrogen peroxide
5) Textile industry: complexation of heavy metals, bleach stabilizer
6) Agrochemicals: Fe, Zn and Cu fertilizer, especially in calcareous soils
7) Hydroponics: iron-EDTA is used to solubilize iron in nutrient solutions.
