Turmeric turns reddish-brown in a solution. What property does this solution have?

Answer and explanation

Correct answer: Basic property

Turmeric contains curcumin, which acts as a natural indicator. In an acidic or neutral medium it generally remains yellow, whereas in a basic medium it develops a reddish-brown colour. Observing this colour change therefore indicates that the tested solution is basic. The result does not show metallic character, and it is inconsistent with a purely neutral or acidic solution under the stated indicator test. Hence option C is correct.
