Explain why stain of curry on a white cloth becomes reddish brown

Answer 1

Hey There!!! So this is your answer.

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. ... When the white cloth is washed in water it turns yellow because water is neutral and the curry contains turmeric which is a indicator.

Hope it helps you!!!

Answer 2

It happens so because turmeric in curry is a natural indicator and when soap(basic in nature) is applied on it, it changes it's color from yellow to reddish brown.
