Vedclass · Answer

(A) disproportionation reaction is a type of redox reaction in which the same element is simultaneously oxidized and reduced.In the reaction $Cu_2O + 2H^{+} 	o Cu + Cu^{2+} + H_2O$:$1$. The oxidation state of $Cu$ in $Cu_2O$ is $+1$.$2$. In the product $Cu$,the oxidation state of $Cu$ is $0$ (reduction).$3$. In the product $Cu^{2+}$,the oxidation state of $Cu$ is $+2$ (oxidation).Since the same element $(Cu)$ undergoes both oxidation and reduction,this is a disproportionation reaction.
