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 gains electrons. Electrons appear on the right 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 when an element in a substance decreases its oxidation number. Electrons appear...

In some chemical reactions, one species loses electrons by transferring them to another species. Consequently, the products have different charges than the reacting elements or ions. Losing electrons is called oxidation and gaining electrons is called reduction. Because free electrons cannot remain in a system, both reduction and oxidation must occur together. Such reactions are termed redox reactions. Just as atoms must be balanced in a chemical reaction, the charges in a redox reaction must also be balanced. Reduction and...

Chemical equations of reduction–oxidation (redox) reactions can be quite nontrivial to balance. To do so, you begin with balancing the number of electrons some particles lose in oxidation and other particles gain in reduction. Consider a reaction between potassium permanganateKMnO4 andhydrochloricacidHCl(aq), which can be used in a lab to produce chlorine gas Cl2. In this reaction, a MnO− 4 ion is reduced to a Mn2+ ion by getting electrons from Cl− and losing its oxygen atoms to bind with H+...
