$KO_2$ is a peroxide which with $H_2O$ forms hydrogen peroxide only.

Vedclass · Answer

(D) The reaction of superoxides with water is given by: $2MO_2 + 2H_2O \rightarrow 2MOH + H_2O_2 + O_2$. Thus,superoxides produce both hydrogen peroxide $(H_2O_2)$ and oxygen $(O_2)$ upon reaction with water. Option $A$ is a true statement. $CrO_3$ is an acidic oxide as it reacts with bases to form chromates. $SnO_2$ is an amphoteric oxide as it reacts with both acids and bases. $KO_2$ is a superoxide,not a peroxide. Furthermore,it produces both $H_2O_2$ and $O_2$ when reacted with water,not just $H_2O_2$. Therefore,the statement in option $D$ is false.
