Hydrogen peroxide, commonly used as a mild antiseptic and bleaching agent, has which chemical formula?

Explanation

Hydrogen peroxide has the chemical formula H2O2, containing one more oxygen atom than a water molecule, which makes it chemically unstable and prone to breaking down into water and oxygen gas over time. This decomposition is why hydrogen peroxide is often seen fizzing or bubbling when applied to a wound, as it reacts with certain enzymes present in blood and damaged tissue. Beyond its use as a mild household antiseptic, hydrogen peroxide is also commonly used as a bleaching agent for hair and various materials.
