Chapter 20 Electrochemistry

Chapter 20 Electrochemistry. Electrochemical Reactions. In electrochemical reactions, electrons are transferred from one species to another. Oxidation Numbers. In order to keep track of what loses electrons and what gains them, we assign oxidation numbers. Oxidation and Reduction.
