3. Introduction- Complexing
Agents
 Association of two or more molecules or ions by non
covalent bond, give a product called complex
 Process of complex formation is called complexation


4. Introduction- Chelating agent
 Chelating agents are chemical compounds that react
with metal ions to form a stable, water-soluble complex.
They are also known as chelants, chelators, or
sequestering agents.
 Chelating agents have a ring-like center which forms at
least two bonds with the metal ion allowing it to be
excreted.
 Chelating agents are usually organic compounds
 Specific chelating agents bind iron, lead, or copper in
the blood and can be used to treat excessively high
