Question

Give any three oxidation reactions of ozone $\left( {{O_3}} \right)$ with chemical equations.

Answer 1

Hint: Oxidation is simply the process of adding oxygen to any compound. In the process of oxidation the electrons are being released from the atom, molecule or an ion. During this process the oxidation state of the atom is also increased.


Complete step by step answer:
Ozone is a triatomic molecule oxygen with the chemical formula $\left( {{O_3}} \right)$. Ozone is formed when the UV radiations from the sunlight react with the molecule of oxygen \[\left( {{O_2}} \right)\]. This reaction can be written as
\[{O_2} + UV \to O + O\]
\[O + {O_2} \to {O_3}\]
The following are the oxidation reactions of ozone.
Lead (II) sulphide reacts with ozone to produce lead (II) sulphate and oxygen. The reaction proceeds at room temperature.
Hydrogen sulphide is oxidized to S. \[{H_2}S + {O_3} \to {H_2}O + S + {O_2}\]. The oxidation number of S in \[{H_2}S\]is \[ - 2\]whereas in S it is zero. So oxidation takes place in the presence of ozone. Hydrogen sulphide reacts with ozone to give water, Sulphur and oxygen gas.
Potassium Iodine is oxidized to iodine \[2KI + {H_2}S + {O_3} \to 2KOH + {I_2} + {O_2}\], when potassium iodine is treated with ozone, the products formed are iodine, oxygen and potassium hydroxide. Iodine ion is oxidized to iodine and ozone is reduced to hydroxide ion.
Additional information: Ozone $\left( {{O_3}} \right)$ is highly reactive gas composed of three oxygen atoms. It is both natural and a man – made product that occurs in the earth’s upper atmosphere (the stratosphere) and lower (the troposphere) atmosphere.

Note:
When inhaled, ozone can damage the lungs. Relatively low amounts can cause chest pain, coughing, shortness of breath and throat irritation.
