. Consider the case of Nitrogen-
In reactant side the oxidation number of nitrogen is +5, while the oxidation number of nitrogen in product side is +4, so the reduction reaction is being carried out in a manner:-
N(+5) + e(-) == N(+4) ———————- (1)
2. Consider the case of Iodine-
In reactant side the oxidation number of iodine is 0 and in product side the oxidation number of iodine is +5, so the oxidation reaction reaction can be written as:-
I2(0) == 2I(+5) + 10e(-) ———————— (2)
Now, balancing reaction (1) and (2) gives us the following equation-
10N(+5) + I2(0) == 2I(+5) + 10N(+4)
Thus, in original form the reaction can be written as-
10HNO3 + I2 == 2HIO3 + 10NO2 + 4H2O
