What colour does turmeric indicator turn in a basic solution?

Answer and explanation

Correct answer: Reddish brown

Turmeric contains curcumin, a natural indicator that remains yellow in acidic or neutral conditions but changes to reddish brown in a basic medium. Therefore, option B is correct. Blue is the familiar change of red litmus in a base, not the normal turmeric response, while green is not the standard result for this indicator.
