PPT-Oxidation Oxidation occurs when an organic loses (donates) one or more electrons to

Mn IIIIV These are to be contrasted with the potentially rapid oxidations that occur with photochemically produced oxidants such as H 2 O 2 O 3 the free radicals such as hydroxyl OH and . 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.. Redox AS 91167. This achievement standard involves . Demonstrating . understanding . of oxidation-reduction . Oxidation-reduction is . limited to:. •oxidation . numbers. •electron . transfer in reactions. Oxidation and Reduction. Oxidation-reduction (. redox. ) reactions involve transfer of electrons. Oxidation – loss of electrons. Reduction – gain of electrons. Both half-reactions must happen at the same time. Definition. If oxidation occurs, then reduction must also occur. Any chemical process in which elements undergo a change in oxidation number is a . Redox reaction. Example. 2Na + Cl. 2. . → 2Na. Redox. ) Reactions. Chapter 20. 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.. REDOX PROCESSES. 9.1. OXIDATION AND REDUCTION. ESSENTIAL IDEA. Redox (reduction-oxidation) reactions play a key role in many chemical and biochemical processes.. NATURE OF SCIENCE (1.9). How evidence is used – changes in the definition of oxidation and reduction from one involving specific elements (oxygen and hydrogen), to one involving electron transfer, to one invoking oxidation numbers is a good example of the way that scientists broaden similarities to general principles.. Reduction. Learning Outcomes. Introduction to oxidation . and reduction. : simple examples . only, e.g. . Na with Cl. 2. , Mg with . O. 2. , Zn . with Cu. 2+. . Oxidation . and reduction . in terms of loss . Energy transfers. You. Your lunch. Overview: Life Is Work. © 2014 Pearson Education, Inc..
