(Pre-Lab Assignment 11: Electrochemistry Identifying Oxidizing and Reducing Agents tors A chemical reaction in which the atoms of the reactants undergo a change in the oxidation state is called a redox reaction. Such reactions involve both oxidation (increase in auxidation state) and reduction (decrease in oxidation state) reactions simultaneously. A reducing agent is the one that reduces another species and at the same time itself gols oxidized. An Oxidizing agent is the one that oxidzes another species and at the...

Choose all of the statements from below which are true about oxidation and reduction. Oxidation and reduction are opposite processes with respect to bookkeeping electrons. Oxidation is what happens when an element in a substance increases its oxidation number. Electrons appear on the left side of an oxidation half reaction. An oxidant is an oxidizing agent, which becomes oxidized during the course of a redox reaction. Reduction is what happens...
