Hydrogen peroxide is a colorless liquid that has a bitter taste and is caustic to skin. Pure H2O2 is a thick liquid like syrup that it quickly decomposes into oxygen and water. Usually it is sold in weaker solutions (most commonly 3 percent), diluted...

Like water (H2, hydrogen peroxide is a compound of hydrogen and oxygen. However, as the its formula (H2O2) indicates, water are quite different. At room temperature, hydrogen peroxide is a pale-blue, syrupy, weakly acidic liquid. Pure, it is a stable...

Hydrogen peroxide (H2O2) is a very pale blue liquid which appears colorless in a dilute solution, slightly more viscous than water. It is a weak acid. It has strong oxidizing properties and is therefore a powerful bleaching agent that is mostly used...
