PPT-Redox Class #1: oxidation reduction reactions made fun

123 Redox explains the chemistry behind batteries and electroplating precious metals onto strong base metals It also explains how to break apart water into hydrogen and oxygen and lots more 4 These 2 reactions are always paired and balanced. 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.. 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.. Oxidation-reduction reactions are integral to many aspects of inorganic chemistry. Building on your existing knowledge of electrochemistry, we will discuss some fundamental aspects of inorganic electrochemistry that you may not have previously considered (and therefore make some new connections to other areas of chemistry) and also introduce and use three diagram-.

Using oxidation numbers, show which element has been oxidised and which has been reduced in this reaction. State the changes in oxidation numbers, including all signs.. Define electrochemistry and a number of important associated items. Split redox reactions into their oxidation & reduction half-equations. Produce balanced redox equations for reactions in acidic solutions.
