What is hydrogen peroxide?

Hydrogen peroxide is a clear, slightly viscous liquid that resembles water. Renowned for its potent oxidizing properties, it serves as an effective bleaching agent. It's famously used in hair lightening—think 'peroxide blonde'—as it inhibits melanin production, whitening hair safely when diluted properly.

Its disinfectant qualities combat bacteria, viruses, and fungi effectively. Historically, high concentrations even fueled rockets. You've likely used it to disinfect cuts, observing the fizzing bubbles—a chemical decomposition where H₂O₂ releases oxygen, forming water (H₂O).
