Hydrogen peroxide (H2O2) is a very reactive substance and can easily break down into water (H2O) and oxygen (O2) when exposed to light. This is a decomposition reaction that is accelerated by light.

The chemical reaction is as follows: 2H2O2 → 2H2O + O2

Dark coloured bottles are used to store hydrogen peroxide to limit its exposure to light, slowing down this decomposition process. This helps to maintain the potency and effectiveness of the hydrogen peroxide over time.

In addition, the breakdown of hydrogen peroxide can be dangerous if it happens too quickly, as it can cause the bottle to explode due to the rapid release of oxygen gas. Therefore, storing it in a dark bottle not only preserves the chemical, but also adds a layer of safety.
