Why should bleaching powder be used carefully on coloured clothes?
Answer and explanation
Correct answer: It has the ability to remove colour
Bleaching powder is used for its oxidising and bleaching action. The active chlorine released from it can oxidise coloured substances, converting them into less-coloured or colourless products. The same action that removes stains can also fade dyes in coloured fabric, so careful use is necessary. Thus option A is correct; the other options do not describe bleaching powder’s chemical action.
