When hydrogen peroxide is exposed to light, it can undergo a process called photodecomposition. This process involves the breaking down of hydrogen peroxide into water and oxygen molecules when it absorbs photons from the light. The reaction is accelerated in the presence of certain catalysts or transition metals, which can further break down the hydrogen peroxide into water and oxygen. This decomposition reaction is why hydrogen peroxide is typically stored in opaque containers to prevent exposure to light.
Hydrogen peroxide decomposes into water and oxygen.
Hydrogen peroxide is stored in dark bottles to protect it from light exposure. Light can cause hydrogen peroxide to break down into water and oxygen, reducing its effectiveness. Storing it in dark bottles helps maintain its potency and shelf life.
Hydrogen peroxide can break down into water (H2O) and oxygen (O2) when exposed to light or heat. This decomposition reaction occurs naturally over time, especially in the presence of certain catalysts like metals.
It means that the concentration of the peroxide is such that for every 1mL of hydrogen peroxide solution, 100mL of oxygen will be produced if fully reduced, catalyzed, exposed to light, heated or decomposed in any manner to the fullest extent. The fullest extent means the end point where every molecule of hydrogen peroxide releases one oxygen atom, and is converted into water.
Hydrogen peroxide is H2O2, so each molecule is composed of two hydrogens and two oxygens. It is somewhat unstable, and left to its own devices will dissociate into water (or H2O) and hydrogen ions (H+); as such, it won't be an effective cleaning agent any longer.
When hydrogen peroxide is exposed to light or heat, it decomposes into water and oxygen gas.

Yes it does. I quote from a medical site: "Hydrogen peroxide can kill bacteria on contact and has been widely used for that purpose. However, straight hydrogen peroxide is unstable and rapidly loses its effectiveness when exposed to air or light." Hope this helps. (:
Mostly because it is sensitive to temperature changes and light, and will decompose back to water & oxygen if it is exposed too too high of temperatures or too much light. Hydrogen peroxide is H2O2, and will readily switch back to H2O and O2, both much more stable molecules.
Yes, hydrogen peroxide can decompose spontaneously over time, especially when exposed to light or heat. This decomposition process releases oxygen gas and water as byproducts.

Hydrogen peroxide (H2O2) is light-sensitive and can decompose when exposed to light. Storing it in colored wax helps to block out light and prevent this decomposition. The colored wax acts as a barrier to light, preserving the integrity and effectiveness of the hydrogen peroxide solution.
Hydrogen peroxide is stored in brown bottles to protect it from light exposure. Light can break down hydrogen peroxide into water and oxygen, reducing its effectiveness. The brown bottle helps to preserve the stability and potency of the hydrogen peroxide.

It is not recommended to store hydrogen peroxide in a red bottle as exposure to sunlight can break down the hydrogen peroxide more quickly, reducing its effectiveness. It is best to store hydrogen peroxide in its original brown bottle or in a container that blocks out light.
It degrades into water and oxygen gas. That is why hydrogen peroxide bottles are brown, to keep light from breaking it down.
