WebJul 20, 2024 · a) The appropriate oxidation numbers are. The only atoms which change are Mn, from +7 to +2, a reduction, and S, from +4 to +6, an oxidation. The reaction is a redox process. SO 2 has been oxidized by MnO 4–, and so MnO 4– is the oxidizing agent. MnO 4– has been reduced by SO 2, and so SO 2 is the reducing agent. b) The oxidation numbers. Web1. The oxidation number of an atom in a free element is 0. 2. The oxidation number of a monatomic ion is equal to its charge. 3. The sum of the oxidation number of all atoms in: A neutral molecule or formula is equal to 0. An ion is equal to the charge of the ion. 4. In their compounds, metals have a positive oxidation number.
