Turmeric turns red in acidic solutions and yellow in basic solutions when tested with pH paper. This color change is due to the chemical structure of turmeric and its reaction with different pH levels.
buy turmeric powder then take a glass of distilled water add 1 teaspoon turmeric powder to it you will notice that the color of the water turns yellow this solution is your indicator
Turmeric powder is commonly used as an indicator. When added to a substance, it turns red in the presence of a base and yellow in the presence of an acid. To test if salt is acidic or basic, mix a small amount of turmeric powder with water and add a pinch of the salt. If the turmeric turns red, the salt is basic; if it turns yellow, the salt is acidic.
I'd suggest (but couldn't establish it from literature) that turmeric powder is yellowish ocra in acidic 'solution', because it gives mustard (made with acetic acid) its yellow color, which is not redish-brown like curcuma is in neutral circumstance.Added:From one scource it says: ' In acidic solutions (pH 8.6) solutions it turns bright red.'
Turmeric is red in basic solutions.
lime juice and soap solutions turn red in turmeric because turmeric is an organic indicator which turns red in acidic or basic solution and lime juice is an acidic solution while soap is a basic solution
Curcuma (turmeric) is red in an alkaline solution and yellow in an acidic solution.
Turmeric contains a compound called curcumin which gives it a vibrant yellow color. In acidic solutions, curcumin changes to a reddish color, while in basic solutions, it changes to a dark brown color. This color change makes turmeric a useful natural indicator for determining the acidity or basicity of a solution.
Natural indicators like red cabbage juice and turmeric can be used to detect basic solutions. These indicators change color in the presence of bases, turning blue or green for red cabbage juice and yellow for turmeric, indicating the basic nature of the solution.
when sugar solution is added to turmeric solution , it turns yellow.
this is because lemon juice is an acid and when we mix with turmeric it turns magenta
