Answer:-
Chlorine gas is passed through a solution of flower to
decolourise the flower
Step-by-step explanation:
Chlorine is used as a bleaching agent because of its oxidising nature.
This nascent "O" is highly reactive in nature and bleaches the substance that comes into its contact.
when flowers are passed through the chlorine solution , it oxidises the solution and removes the colour from the flower.
This property also made its use as water-disinfectant reagent.
Chlorination is done to make the water useful for drinking
It kills the harmful bacteria present in the water.
