Final answer:
Complexing agents, such as metal ions and chelating anticoagulants, have important applications in various fields like medicine and water softening.
Step-by-step explanation:
Complexing agents, such as metal ions like silver and mercury and chelating anticoagulants like EDTA, are important in various applications. Complexing agents, such as metal ions and chelating anticoagulants, have important applications in various fields like medicine and water softening.
They can be used as drugs to treat heavy metal poisoning by forming water-soluble chelates that can be eliminated by the body's kidneys. Additionally, complexing agents like EDTA are used in water softening, as preservatives to prevent reactions that change the color of food, and in paper production, textiles, and detergents for sequestering metal ions.
