Hydrogen peroxide is a clear, colorless, noncombustible liquid that is commonly used in households and hospitals. Here are a few facts to help you understand its uses:

1. Hydrogen peroxide (H2O2) is water (H2O) with an extra oxygen molecule (O) which enhances the oxidation power of hydrogen peroxide and helps kill germs.
2. The medical-grade hydrogen peroxide with a strength of 3% (3% hydrogen peroxide and 97% water) is the most effective and is commonly used in households.
3. Hydrogen peroxide should be used in well-ventilated areas and the handler should wear gloves as it has toxic effects if inhaled and can cause irritation if it comes in contact with eyes and skin.
4. Hydrogen peroxide is effective in removing germs and pesticides from fruits and vegetables. It can also be used to clean and disinfect kitchens and bathrooms.
5. Hydrogen peroxide should not be used on open wounds as it can cause skin irritation and inflammation which may interfere with wound healing.
6. Hydrogen peroxide should not be used on acne or acne-prone skin as it exacerbates acne and may interfere with the therapeutic effects of acne medications containing benzoyl peroxide.
7. Hydrogen peroxide should not be used beyond its expiration date. If you find that the solution is no longer producing foam or bubbles, discard it and purchase a new one.
