Vedclass · Answer

(B) $Pb_3O_4$ is insoluble in water and does not react with it.$2 KO_2 + 2 H_2O \rightarrow 2 KOH + H_2O_2 + O_2 \uparrow$. Potassium superoxide $(KO_2)$ reacts with water to liberate oxygen gas.$Na_2O_2 + 2 H_2O \rightarrow 2 NaOH + H_2O_2$. Sodium peroxide produces hydrogen peroxide,not oxygen gas.$Li_2O_2 + 2 H_2O \rightarrow 2 LiOH + H_2O_2$. Lithium peroxide produces hydrogen peroxide,not oxygen gas.
