Summary. Chemical reactions in which electrons are transferred are called oxidation-reduction, or redox, reactions. Oxidation is the loss of electrons. Reduction is the gain of electrons. Oxidation and reduction always occur together, even though they can be written as separate chemical equations.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.Whether an amphiprotic species behaves as an acid or as a base depends on the equilibrium constants for the competing reactions.
