Turmeric is a natural indicator which turns:A.Yellow in acid and red in baseB.Yellow in base and red in acidC.Blue in acid and red in baseD.Blue in base and red in acid

To determine how turmeric behaves as a natural indicator, we need to understand how it interacts with acids and bases.

Turmeric contains a compound called curcumin, which exhibits color changes in response to pH levels:

In acidic solutions: Turmeric turns yellow. This is because the curcumin present in turmeric reacts with the hydrogen ions (H+) in the acid, leading to a change in color.

In basic (alkaline) solutions: Turmeric turns red. The reaction with hydroxide ions (OH-) causes this color change.

Based on this information, we can analyze the answer choices:

A. Yellow in acid and red in base
B. Yellow in base and red in acid
C. Blue in acid and red in base
D. Blue in base and red in acid

The correct answer is A: Yellow in acid and red in base.
