Question

For chelating agents is typical:

a) they can be used in the treatment of some intoxications
b) they form complexes with heavy metals
c) once formed chelates should be not-toxic
d) once formed chelates should be water-soluble

Answer 1

Chelating agents are compounds that can form complexes with heavy metals and are used in the treatment of some intoxications. These complexes are typically water-soluble and can be eliminated from the body.

Step-by-step explanation:

Chelating agents typically form complexes with heavy metals. These complexes are formed when the chelating agent binds to the metal ion through multiple donor atoms. One example of a chelating agent is the ligand EDTA, which forms hexadentate complexes with metal ions. Chelating agents are often used in the treatment of some intoxications, as they can bind to and sequester metal ions, preventing them from reacting and causing harm. They can also be water-soluble, which allows for easier elimination from the body.
