Question

How ozone can be prepared?

Answer 1

• Ozone ( ${\mathrm{O}}_3$) is an allotropic form of oxygen.
• To prepare ozone, take pure, cold, and dry oxygen in a Siemen's ozonizer.
• Pass a silent electric discharge through it.
• In this process we obtain ozone gas of up to 15% concentration.
• The chemical equation is; $$\begin{gathered} 3{\mathrm{O}}_2\left(\mathrm{g}\right)\to 2{\mathrm{O}}_3\left(\mathrm{g}\right) \\ \mathrm{oxygen}\mathrm{ozone} \end{gathered}$$
