1 Redox reactions may involve the transfer of electrons between chemical species. 2  The reaction that occurs when In which I 2 is reduced to I-and S 2 O 3 2- (thiosulfate anion) is oxidized to S 4 O 6 2- provides an example of a redox reaction :
Redox Reactions. 1  For atoms in their elemental form, the oxidation number is 0. 2  For ions, the oxidation number is equal to their charge. 3  For single hydrogen, the number is usually +1 but in some cases it is -1. 4  For oxygen, the number is usually -2.
