Solution:

Hydrogen peroxide is a chemical used in oxidation reactions, treatment of various inorganic and organic
pollutants, bleaching processes in pulp, paper and textile industries and for various disinfection applications. It
is a mono propellant, which, when purified, is self-decomposing at high temperatures or when a catalyst is
present. Decomposing to yield only oxygen and water(disproportionation), hydrogen peroxide is one of the
cleanest, most versatile chemicals available.
