Question

Rohan got a tumeric stain on his clothes while eating food. when he tried to wash it off with soap, the stain turned red. why?

Answer 1

Turmeric is a natural indicator. It retain its yellow colour with acidic and neutral solution but turn red in contact of basic solution. Soap is basic in nature. So when we wash the cloth with stain of haldi with soap it change its colour from yellow to red.
To remove the stain from cloth, it should be treated either with liquid detergent as it is non-ionic. Also, it can be treated with vinegar or baking soda to fade the stain.

Answer 2

Answer:

Becoz turmeric is an indicator which gives red colour with a base since soap is a base so we get red colour......

Hope it help you ✌️❣️
