Question

why does a vegetable strain turn reddish-brown when washed with soap solution.​

Answer 1

Answer:

✍️Cooked vegetables or vegetable curry contain turmeric powder and soap is basic in nature. Turmeric is a natural indicator which changes its yellow colour into reddish brown when it comes in contact with a solution of base. Hence, when soap (which is basic in nature) is scrubbed on the stain, the stain turns red.

Answer 2

Cooked vegetables or vegetable curry contain turmeric powder and soap is basic in nature. Turmeric is a natural indicator which changes its yellow colour into reddish brown when it comes in contact with a solution of base. Hence, when soap (which is basic in nature) is scrubbed on the stain, the stain turns red. When the cloth is washed with plenty of water, the soap is removed and the yellow colour of the stain reappears.
