What can break down hydrogen peroxide?
Yeast is an organism that contains a special chemical called catalase that can act as a catalyst to help break down hydrogen peroxide. This means that if you mix yeast with hydrogen peroxide, the hydrogen peroxide will rapidly break down into water and oxygen gas. The oxygen gas forms bubbles.
How long will hydrogen peroxide stay good?
Hydrogen peroxide retains its effectiveness for up to three years in an unopened container and six months in an opened container. Expired hydrogen peroxide is not detrimental, but it does lose potency. A simple test to see if hydrogen peroxide is still effective can be performed by pouring a small amount into a bathroom sink.

This type of hydrogen peroxide can cause minor symptoms to occur if ingested, touched, or inhaled. More potent forms of hydrogen peroxide can be dangerous — or even fatal — to drink, breath in, or touch. Hydrogen peroxide is not a cure for cancer, HIV, or any other disease.
Is hydrogen peroxide a good reducing agent?
Why can hydrogen peroxide act as both an oxidising agent and a reducing agent? Hydrogen peroxide has the ability to gain or lose electrons, as its oxygen atoms are in the -1 oxidation state. By gaining electrons they can go to the -2 oxidation state, and by losing electrons they can go to the zero oxidation state (the element)

What is peroxide made of?
Peroxide is a solution made up of hydrogen and oxygen. It is a strong oxidizer and can be used as a cleaning agent and to prevent infections. When used topically, this antiseptic foams due to the enzyme catalase. As the catalase comes in contact with the skin it turns the hydrogen peroxide into water and oxygen gas.
