Question

Explain the method of preparation of ozone gas by electric discharge method.

Hint:

Always use silent discharge to avoid decomposition of ozone.

Answer 1

Step 1: Principle.
Electric discharge splits O\(_2\) molecules into oxygen atoms, which combine with O\(_2\) to form O\(_3\).
Step 2: Reaction.
\[ 3 O_2 \xrightarrow{\text{electric discharge}} 2 O_3 \] Step 3: Apparatus.
Silent discharge (ozoniser) is used to prevent decomposition of ozone by spark.
Step 4: Conclusion.
Thus, ozone is prepared by passing silent electric discharge through oxygen.
