3. When soap is scrubbed on a stain of curry on a white dloth,why does it become reddish brown, and turns yellow again2when the cloth is washed with plenty of water? |

Answer» HIT THE LIKE BUTTON The stain of curry on a white cloth turns reddish brown when soap is rubbed on it because curry contains turmeric which is a indicator and soap is basic in nature. So, soap is reacting on curry (turmeric) which turns reddish brown in colour. When the white cloth is washed in water then it turns yellow because water is neutral and the curry contains turmeric which is a indicator. The water turns turmeric back to yellow. Thanks |
