The bleaching action of chlorine is permanent whereas the bleaching action of sulphur dioxideis temporary. In this context:-
Give a reason why chlorine is not used to bleach silk.
The bleaching action of chlorine is permanent whereas the bleaching action of sulphur dioxideis temporary. In this context:-
State the similarity in the use of Sulphur dioxide and chlorine as bleaching agents.
The bleaching action of chlorine is permanent whereas the bleaching action of sulphur dioxideis temporary. In this context:-
Explain the bleaching action of sulphur dioxide with the help of chemical equations.
IN the presence of moisture, sulphur dioxide produces nascent hydrogen which reduces many coloured substances to colourless compounds. The colouring matter combines with nascent hydrogen to form colourless reduction product.
SO2(g) +2H2O ---> H2SO4(aq) +2|H|
Coloured substance +|H| --> Colourless reduction product.
The bleaching action of chlorine is permanent whereas the bleaching action of sulphur dioxideis temporary. In this context:-
Why is bleaching by sulphur dioxide only temporary ?
