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+...

When balancing redox reactions using the half-reaction method, several conditions apply. Check all the REQUIRED conditions. When combining half-reactions, you must make sure the total number of electrons in each half cancels out. Oxidizing agents gain electrons. Electrons are reactants in the reduction half-reaction The number of electrons transferred by a reducing agent can be found by counting oxidation numbers. For polyatomic ions, the oxidation number of the central atom is the same as the charge. The total charges of...

Part IV: Balancing Redox Reactions in Acidic and Basic Solution General rules for balancing redox reactions in acidic or basic solution: 1. Divide the redox reaction into two half-reactions. One that contains the element that gets Oxidized and one that contains the element that gets reduced. 2. Focusing on one half-reaction at a time, balance all non-H and non-0 atoms. 3. Balance the O atoms by adding water molecules to the side with too few oxygens 4. Balance the H...

In addition to mass balance, oxidation-reduction reactions must be balanced such that the number of electrons lost in the oxidation equals the number of electrons gained in the reduction. This balancing can be done by two methods: the half-reaction method or the oxidation number method. The half-reaction method balances the electrons lost in the oxidation half-reaction with the electrons gained in the reduction half-reaction. In either method H2O(l), OH?(aq), and H+(aq) may be added to complete the mass balance. Which...
