Hydrogen peroxide is always stored in dark plastic containers away from sunlight because in the presence of warm conditions and UV light hydrogen peroxide can decompose into water and oxygen because the oxygen oxygen bond in molecule is unstable.
Gunjan bharti 15 Points. Hydrogen peroxide is a highly reactive compound so it can easily react with heat or light. To prevent it from reaction it kept in coloured or dark bottle. Which is why when you buy hydrogen peroxide , it comes in a brown plastic bottle. Here's why: Many chemical compounds break down over time, and hydrogen peroxide is no exception. Although it is extremely stable, the solution can start to decompose when it comes in contact with light and heat. The brown bottle in your medicine cabinet is a bulwark against those two catalysts.
Light cannot penetrate the tint of the brown bottle, preventing oxidation, which can result in an increase in temperature.
As peroxide breaks down, it gets hotter. As a result, the compound's decomposition rate accelerates. In fact, for every degree Celsius rise in temperature, the decomposition rate nearly doubles. Moreover, if some sort of contaminant, such as dust, silver , lead or other metal, gets into the solution, it can spark a fire, although the solution itself is not explosive. Those in the industry must handle hydrogen peroxide with care. If the solution is in a closed system, such as a storage tank, and it starts to break down, pressure can build up causing the tank, a pipe or a line to rupture.
The good news is that the bottle of peroxide in your medicine cabinet contains only a 3 percent solution, far less than the 35 percent that the food industry uses, for example.
You may also notice that peroxide never comes in a clear, glass container. That's because glass bottles may contain dissolved alkali metal ions that can react with the solution. Sign up for our Newsletter! Mobile Newsletter banner close. Mobile Newsletter chat close.
