When manganese dioxide is added to hydrogen peroxide, oxygen and water are formed. Manganese dioxide acts as a catalyst to speed up the decomposition of hydrogen peroxide into oxygen and water. The chemical formula of hydrogen peroxide is H2O2, the chemical formula for oxygen is O2, and the chemical formula for water is H2O.
Decomposition of H2O2 with MnO2 - UW Dept. of Chemistry
Use a vase or cover a pop bottle with foil so students cannot see inside the bottle. Place 30 mL of 30% hydrogen peroxide (USE CARE!) in the bottle. Carefully remove the tea from a tea bag and in its place put in solid manganese dioxide. Now put the "tea bag" in the bottle such that it dangles above the hydrogen peroxide.
What happens when you mix manganese dioxide with hydrogen ...
Manganese dioxide will catalyze the release of oxygen when added to hydrogen peroxide. The peroxide, H2O2, becomes H2O + O. The oxygen escapes as a gas, leaving water. Adding a small amount of hydrogen peroxide to a larger quantity of manganese dioxide would quickly (perhaps violently, depending on the concentration of the H2O2) release oxygen…
