Both must occur together for it to be a redox reaction, but if only one occurred it would be called an "oxidation half-reaction" or a "reduction half-reaction." Finding these "half reactions" are often essential to solve a redox reaction problem, but they are NOT redox reactions themselves. I hope that helps!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.Oxidation-reduction (redox) reactions involve the transfer of electrons from one atom to another. Oxidation numbers are used to keep track of electrons in atoms. There are rules for assigning oxidation numbers to atoms. Oxidation is an increase in oxidation number (loss of electrons); reduction is a decrease in oxidation number (gain of electrons).oxidation number, also called oxidation state, the total number of electrons that an atom either gains or loses in order to form a chemical bond with another atom.. Each atom that participates in an oxidation-reduction reaction is assigned an oxidation number that reflects its ability to acquire, donate, or share electrons.The iron ion Fe 3+, for …An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species.
