WebAn oxidation reduction (redox) reaction happens when electrons are transferred between atoms. A loss of electrons is called oxidation, and we say that atom has become oxidized. A gain of electrons is called reduction, and we say that the atoms has become reduced.

(1) S ==> SO 2 [burning sulphur - oxidised] (2) CH 4 ==> CO 2 + H 2 WebFe 2 O 3 + 3 CO --> 2 Fe + 3 CO 2. The oxidation state of oxygen is –2 in all compounds, therefore oxygen is neither oxidized or reduced. The oxidation state of iron decreases from +3 in Fe 2 O 3 to zero in the uncombined element Fe. Therefore, iron gains electrons and Fe 2 O 3 is the oxidizing agent. Iron is reduced. fran mccaffery meter
