ions. The process which involves simultaneous oxidation and reduction reactions is defined as the redox reaction. The first reaction converts copper metal into CuO, Hydrochloric acid, the compound that delivers the hydrogen ions to the reaction, is acting as an oxidation agent because it oxidizes magnesium to magnesium cations while being reduced in the process. Reducing Agent/Reducing Agent Pairs, The Relative reaction mg 2hcl mg+hcl=mgcl2+h2 balanced equation hcl + mgo. ion). This is an exothermic reaction, meaning that the forming of the bonds MgCl2 and H2 gives off heat. - In CH3OH, the oxidation number of C is -2, , that of O is-2, and that of H is +1. Reactants: Mg Names: Magnesium. We assign oxidation numbers (ONs) to elements using these rules: Rule 1: The ON of an element in its free state is zero examples are Al, Zn, H, O, N. This is an ion and so the sum of the oxidation states is equal to the charge on the ion. The oxidation state of a simple ion like hydride is equal to the charge on the ionin this case, -1. agent (CuO).
