Give the reason for the bleaching action of Cl_(2)

Answer»

Solution :In presencee of moisture or in aqueous solution, `Cl_(2)` libertes NASCENT oxygen.
`Cl_(2) + H_(2)O rarr 2 HCl underset("Nascent oxygen")([O])`
This nascent oxygen BRINGS about the oxidation of coloured substances PRESENT in vegetable and organic matter to colourless substances.
Coloured SUBSTANCE + O `rarr` Colourless substance
Thus, the bleaching action of `Cl_(2)` is due to oxidation. Since the bleaching effect of `Cl_(2)` is permanent, it is used to bleach cotton and textiles and WOOD pulp for manufacture of paper and rayon.
