Beginning Unit 4. Salt on icy roads can make driving safer, but the salt that clings to the metallic parts of cars can cause them to corrode or rust relatively quickly. . This corrosion is one example of a chemical reaction called oxidation-reduction. You will learn about oxidation-reduction reactions.. Part 1 . Zagazig. University . Clinical Pharmacy . Programe. .

The oxidation state is a “measure of the degree of oxidation of an atom in a substance” and it is the fundamental key to understanding redox reactions, reaction mechanisms, catalysis, etc. I (work funded through the Great Lakes Restoration Initiative).
