EDTA complex formation can be used in treating metal poisoning. By the support of chemical equation, explain how one can be cured from lead poisoning?

Lead poisoning occurs when the body accumulates high levels of lead, typically from exposure to lead-based paints, contaminated water, or other sources. EDTA (ethylenediaminetetraacetic acid) is a chelating agent that can bind to heavy metals like lead and form stable complexes that can be excreted from the body.

The chemical equation for the formation of the lead-EDTA complex is:

Pb2+ + EDTA4- → Pb(EDTA)2-

In this reaction, the lead ion (Pb2+) binds to four EDTA molecules (EDTA4-) to form the lead-EDTA complex (Pb(EDTA)2-). This complex is then excreted from the body through urine, effectively removing the lead from the system and treating lead poisoning.

By administering EDTA as a chelation therapy, healthcare providers can help patients with lead poisoning eliminate the toxic metal from their bodies and prevent further health complications associated with lead exposure.
