Advantages and disadvantages of perborate and chlorine bleaches must be listed Concept Introduction: A bleaching agent is a substance that is used to decolorize other materials. Colored materials have a group of atoms in their chemical structure that can absorb visible light of a particular color. These groups of atoms are known as chromophores. Chromophores absorb visible light of a particular color and reflect the complementary color. Bleaching agents destroy the chromophores, by either oxidation or reduction. Bleaching agents such as hypochlorite are oxidizing bleaches. Oxidizing bleaches work by breaking the chemical bonds in the chromophores of substances. This is done by oxidizing the chromophore breaking the chemical bonds change the chromophore of a substance thereby decolorizing it. Bleaches are either chlorine based, or oxygen based. Chlorine bleaches mainly contain hypochlorite and oxygen bleaches mainly contain borates.
