Question

Mix soap solution in turmeric powder and write your observation.

Answer 1

If we put 'soap solution' on turmeric paper it will turn to red color. We know that acids are 'sour substances' which have corrosive nature and change 'blue litmus' to red. Similarly bases are bitter in taste and change 'red litmus to blue'. Here litmus paper is an indicator which changes color with acid and base.

Answer 2

Answer:

Soap contains sodium hydroxide which is a base and turmeric contains a mild acid so whenever soap solution is added to the turmeric paste it will give reddish brown colour
