Concept introduction: The oxidation state or number in a compound is the charge present on the individual atom if the all bonds are assumed to be ionic. The net charge present on a neutral compound is always zero. The charge present on the ionic compound is equal to some of the charges of all the atoms present in that ionic compound. Oxidation is a process in which there is a loss of electron during a reaction. Reduction is a process in which there is a gain of electron during a reaction. The reaction is balanced when the number of atoms and charge are balanced on both the sides of the reaction. To determine: The balanced reaction of the given half reaction and the identification of the oxidation-reduction half-reactions out of the given equation.
