involve changes in the oxidation state (oxidation number) of at least two of the species involved in the reaction.
• The oxidation
numbers are assigned to atoms on the basis of the rules given
below.
ASSIGNMENT OF OXIDATION STATES: RULES
(i) For anions and cations, the oxidation number is equal to the charge on the ion.
