Expired Hydrogen Peroxide Decomposition
On the change of expired hydrogen peroxide
There is hydrogen peroxide in the world, which is used for disinfection and bleaching. However, when it expires for a long time, its properties will change.
Hydrogen peroxide, chemical name hydrogen peroxide, is normally a colorless liquid with strong oxidizing properties. When it expires, the appearance of decomposition gradually appears. Capped hydrogen peroxide is unstable, and under the catalysis of light, heat or impurities, it is divided into water and oxygen.
Expired hydrogen peroxide, microbubbles can be seen in the bottle, which is a sign of oxygen escape. The rate of decomposition varies with the environment. If the temperature is high, the light is strong, or there are impurities, the decomposition will be accelerated. And during the decomposition process, a small amount of heat may be produced.
From this perspective, expired hydrogen peroxide is no longer in its initial state, and its oxidation power is gradually weakening. When used for disinfection, its effectiveness is not as good as before, and it is difficult to kill germs; when used for bleaching, the power of color change is also reduced. When used, it may be difficult to achieve the expected effect.
Therefore, for hydrogen peroxide, when the time limit is observed, do not use it when it expires. One is not effective, and the other may be due to changes in nature, resulting in unexpected diseases. For things used, follow the rules and observe the period, so that the security can be complete and the effect can be achieved.
