Q. When $Cl_2$ gas reacts with hot and concentrated sodium hydroxide solution, the oxidation number of chlorine changes from :

Solution:

Chlorine reacts with hot and concentrated NaOH solution and dispropositionates into chloride $(Cl^-)$ and chlorate $(CIO^-_3)$ ions.
In the reaction oxidation state of chlorine changes from 0 to -1 and 0 to + 5.
In dispropositionation, the same element undergoes oxidation as well as reduction simultaneously.
