Can turmeric act as an indicator?

Yes, turmeric can act as a pH indicator due to the presence of curcumin, which changes color in response to pH levels. In acidic solutions, turmeric appears yellow, while in alkaline conditions, it can turn reddish-brown. This property makes turmeric a useful, natural alternative to synthetic pH indicators in various applications. However, its color change is not as distinct or reliable as some commercial indicators.
