PPT-Oxidation and Reduction

Lecture 9 Law of Mass Action Important to remember our equation describes the equilibrium condition At nonequilibrium conditions it is called the reaction quotient Q Written for the reaction H. Part 1. Notes 11. 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.. 11EGS . 2014. Introduction. Corrosion may be defined as the chemical deterioration of a material. . Metals are the key materials that are subject to corrosion, but polymers and ceramics can also corrode. . Oxidation and Reduction. IB Core Objective. 9.1.1 Define . oxidation. and . reduction. in terms of electron loss and gain.. Define: Give the precise meaning of a word, phrase or physical quantity..

C. +. __O. 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 Kaitlin Brunik.
