Chlorine water has both oxidising as well as bleaching properties ? Explain.

Explanation

Chlorine reacts with water to evolve nascent oxygen which brings about both oxidation and bleaching.
As oxidising agent :
`{:(Cl_(2)+H_(2)O to 2HCl+O),(underline(SO_(2)+H_(2)OtoH_(2)SO_(4)" ")),(Cl_(2)+SO_(2)+2H_(2)Oto2HCl+H_(2)SO_(4)):}`
As bleaching agent :
`Cl_(2)+H_(2)O to 2HCl+(O)`
