What is the Redox reaction?
A chemical reaction involving oxidation and reduction processes is called a redox reaction. Oxidation may be defined as the process in which a species(atom, molecule or ion) increases oxidation number by losing one or more of electrons.
The substance undergoing oxidation is called the reducing agent. Reduction, on the other hand, is a process in which a species(atom, molecule or ion) decreases oxidation number by gaining one or more electrons. The species undergoing reduction is called an oxidising agent. Neither oxidation nor reduction can take place alone. These are complementary processes and occur side by side. Redox reaction can, thus, be termed as the chemical reaction involving the transference of electrons from reducing agent to oxidizing agent.
Some examples of redox reactions are as follows :
1. Zn(s) power 0 + Cu(aq) power 2+ -------> zn 2+ power (aq) + Cu(s) power 0
2. I2(s) power 0 + 10HNO3 (l) power +5------> 2HIO3 Power (+5) + 10NO2 Power (+4) + 4H20
