chlorine water releases nascent oxygen .......
coloured material + [O] ----------> colourless material
this bleaching action is permanent......
SO2 + 2 H2O ---> H2SO4 + 2 [H]
coloured material + [H] ---------> colourless material
this bleaching action is temporary as the colourless material can be aerially oxidised to get back its colour...........
