PPT-5. Electrochemistry 5.1: Balancing oxidation-reduction reactions

Define electrochemistry and a number of important associated items Split redox reactions into their oxidation amp reduction halfequations Produce balanced redox equations for reactions in acidic solutions. 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.. Chemical Equations. This equation means:. 4 Al(. s. ) + 3 O. 2.
