An example of disproportionation reaction is:

Step-by-step solution

A disproportionation reaction is a redox reaction in which the same element in a single oxidation state is simultaneously oxidized and reduced. In the reaction 2 H ₂ O ₂ 2 H ₂ O + O ₂ , the oxidation state of oxygen in H ₂ O ₂ is -1 . In the product H ₂ O , the oxidation state of oxygen is -2 , which corresponds to reduction. In the product O ₂ , the oxidation state of oxygen is 0 , which corresponds to oxidation. Since the same element (oxygen) is both oxidized and reduced, this is a disproportionation reaction. A
