H2O2

Hydrogen peroxide (H₂O₂) is a chemical compound composed of two hydrogen atoms and two oxygen atoms. It appears as a pale blue liquid in concentrated form and is commonly used as an antiseptic for cleaning wounds, thanks to its ability to kill bacteria and fungi. It also acts as a bleaching agent in hair dyes and paper production. When applied, it releases oxygen, creating bubbles that help lift dirt and debris. In lower concentrations, it’s safe for household use, but higher concentrations require careful handling due to its strong oxidizing properties and potential to cause burns.
