While sulphur dioxide and hydrogen peroxide can act as oxidising as well as reducing agents in their reactions, ozone and nitric acid act only as oxidants. Why?

Solution:

In sulfur dioxide \left(S O_{2}\right) the oxidation no. of \mathrm{S} is +4 and the scope of oxidation no. of sulfur is from +6 to -2.

Consequently, S O_{2} can go about as a decreasing and oxidizing specialist.

In hydrogen peroxide \left(H_{2} O_{2}\right) the oxidation no. of 0 is -1 and the scope of the oxidation no. of oxygen is from 0

to -2. Oxygen can some of the time achieve the oxidation no. +1 and +2.

Accordingly, \mathrm{H}_{2} \mathrm{O}_{2} can go about as a decreasing and oxidizing specialist.

In ozone \left(O_{3}\right) the oxidation no. of 0 will be 0 and the scope of the oxidation no. of oxygen is from 0 to -2. Consequently,

the oxidation no. of oxygen just declines for this situation.

Accordingly, O_{3} acts just as an oxidant

In nitric corrosive \left(H N O_{3}\right) the oxidation no. of nitrogen is +5 and the scope of the oxidation no. that nitrogen can

have is from +5 to – 3. Consequently, the oxidation no. of nitrogen can just diminish for this situation.

Accordingly, H N O_{3} acts just as an oxidant.
