WebFor a reaction to be a redox reaction, there must be both an oxidising and reducing agent present Some substances can act both as oxidising and reducing agents - look at the two … Webreduction: a decrease in the number of oxidation of a chemical species, generally due to an acquisition of electrons by the species. Reduction: oxidizing species + n e- → reduced species. Oxidation: reducing species → oxidized species + n e-. being n the number (or moles) of electrons exchanged during the reaction, equal in both half-reactions. rage 1 remake https://germinofamily.com
