Hydrogen Peroxide and manganese Dioxide?

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. The manganese dioxide remains unchanged. Concentrated hydrogen peroxide reacts very rapidly, even violently, when MnO2 is added; but a dilute solution will release its oxygen more slowly and steadily; making it useful as an oxygen generator for laboratory experiments.


What does manganese dioxide and hydrogen peroxide form?

H2O2, or Hydrogen Peroxide is combined with MnO2, Manganese Dioxide, to form H2O, water, and O2, oxygen gas. The Manganese Dioxide serves as a catalyst in this reactions since it is not a reactant, but sets the reaction in motion. Therefore, when writing the chemical equation, one should place MnO2 beneath the yield sign. One's balanced chemical equation should look like this: a. 2H2O2(L) ==> 2H2O(L) + O2(g) MnO2(s)


What is the role of manganese dioxide in the laboratory preparation of oxygen?

The manganese dioxide is a catalyst which speeds up the break down of the H2O2 (Hydrogen Peroxide) to release the O2.


Oxygen gas can be formed by using what compound in the presence of manganese dioxide?

Hydrogen peroxide (H2O2)


Does manganese dioxide change when is added to hydrogen peroxide?

No it does not have any change in its chemical composition at all


What happens when manganese dioxide is added to hydrogen peroxide?

The reaction is speeded up....and water and oxygen are the products.
