OVERVIEW
You will first learn the importance of the form in
which an element occurs in solution to properties such as toxicity.
After that, a number of definitions and concepts required in the
remainder of Lesson 5 are introduced. Finally, you will learn that
complexation reactions can be studied via titration, just as
acid-based reactions.
KEY CONCEPTS
-
The importance of chemical speciation to
toxicity, bioavailability, mobility and solubility
-
The definition of terms including but not
limited to: ligand, central atom, multidentate,
chelation, polynuclear, species, coordination number,
ligand number, colloid, stability constants
-
The concept of metal titrations
