Oxidation: 1. Gain of oxygen 2. Increase in oxidation number Reduction: 1. Loss of oxygen 2. Decrease in oxidation number Ex: (Very, Very Important) A(ox state = +2) + B (ox state = +1) A(ox state = 0) + B (ox sate = +3) Oxidizing agent is reduced. Reducing agent is oxidized. Ex: reduction of hematite to iron by carbon monoxide REDOX REACTIONS Oxidation and reduction reactions

Oxidation and reduction half-reactions Ex: Ni +2 (aq) + IO 4 - (aq) Ni +3 (aq) + I - (aq) Rules for dividing into Oxidation and reduction half-reactions 1. Calculate the oxidation numbers of all the elements in the reaction. 1. List out the elements (followed by corresponding compounds) that are undergoing oxidation and reduction. 1. Write out the reactants and products for both the reactions.

Balancing redox reactions Rules(reactions in acidic medium): 1. Divide the reaction into oxidation and reduction half-reaction. 2. Balance the number of atoms of all the elements other than oxygen and hydrogen. 1. Balance oxygens by adding water molecules. 2. Balance hydrogens by adding H
