Sodium peroxide and hypochlorous acid can be bleached for the same reason, both because of their strong oxidation. The specific principle is introduced as follows:

1, bleaching principle of sodium peroxide;

During the reaction of sodium peroxide with water, hydrogen peroxide will be produced. Because of its strong oxidation, some reagents such as magenta will be bleached. Therefore, it is irreversible to put sodium peroxide into phenolphthalein solution, which first turns red and then fades.

2. The principle of hypochlorous acid bleaching:

Hypochloric acid can oxidize reducing substances (such as Na? So what? ，FeCl？ ，KI，C？ h？ o？ N (litmus) and so on. ), can make colored cloth strips and magenta fade, and make litmus solution become colorless liquid.

Extended data:

Among them, other uses of sodium peroxide are introduced:

1, can it be used with CO? Action, release o? .

2Na？ o？ + 2CO= 2Na？ CO？ +O？

According to this characteristic, it can be used in anoxic occasions such as mines, tunnels, diving or spaceships to reduce co? Then it is converted into oxygen for breathing.

2. Sodium peroxide can be used to remove O? H in？ O and CO? impurity

3. Sodium peroxide can also be used for disinfection, sterilization and bleaching. Commonly used as bleach, bactericide, disinfectant, deodorant, oxidant, etc. In industry.

4. Melted sodium peroxide is a very good oxidant, which can oxidize Fe into ferrate at room temperature and even convert organic matter into carbonate.
