Why do turmeric stains turn red when soaked in detergent solution?
It is because the turmeric contains a compound called cucumine.cucumine reacts with the fatty acid in the soap/detergent and thence the color of the combination changes to red.
Why does turmeric stains turn red when wash?
Turmeric stains turn red when washed due to a chemical reaction involving the curcumin pigment in turmeric. When turmeric comes into contact with alkaline substances, such as soap or certain detergents, the pH change can alter the structure of curcumin, causing it to shift from its original yellow color to a reddish hue. This phenomenon is often more noticeable on certain fabrics or surfaces.
What if turmeric solutions turns green?
If turmeric solutions turn green, it may indicate a chemical reaction or the presence of certain impurities. Turmeric contains curcumin, which can change color in response to pH changes, potentially leading to a green hue in alkaline conditions. This color change might also occur if the turmeric is mixed with other substances that alter its chemical properties. It's advisable to check the quality of the turmeric used and ensure that it hasn't been contaminated.

How does turmeric work as natural indicator?
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.
How do you get back the color of turmeric after the reaction of turmeric and calcium hydroxide solution?
add lemon juice
How does turmeric changes it colour in an alkaline medium?
Turmeric contains pigments called curcuminoids, which change color at different pH levels. In an alkaline environment, the curcuminoids tend to turn a more vibrant red or pink color, due to a change in their chemical structure. This color change is reversible and is often used as an indicator in laboratory experiments.
How you use lovibond tinctometer for turmeric colour test?
To use a Lovibond tintometer for a turmeric color test, first prepare a turmeric solution by dissolving a known quantity of turmeric powder in distilled water or an appropriate solvent. Next, fill the tintometer cuvette with the solution and place it in the tintometer, ensuring proper alignment. Adjust the color filters until the reading matches the color of the turmeric solution, allowing you to quantify its color intensity based on the Lovibond scale. Finally, record the color value, which can be used to assess the quality or concentration of the turmeric.
