Want this question answered?
the turmeric solution changes into red in colour as turmeric solution is an indicator and reveals that soap solution is a base.
It is because turmeric contains an acid (tartaric acid), while the soap contains a base (sodium hydroxide). When an acid reacts with a base, neutralization reaction takes place and the stain becomes neutral.
The color become red.
try regular dishwashing liquid soap (like Ajax)
Apply Kerosene on the paint stain and rub it with hand and brush, then wash it with soap

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
You CAN pre-treat the stain (quickly) by using detergent and a brush, and then washing it in hot water, and drying in direct sunlight. Turmeric is a dye, using water before detergent can spread the stain, and make it permanent (yellow)
When the stain is still fresh, apply white wine. The color begins to disappear and then all you're left with is the wet part of the stain. If the stain is dry, then use a little soap that is safe on the material (I would try Palmolive) and hydrogen peroxide. Spray, dab, or pour the mixture on the stain. Been there done that!
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.
the curry contains turmeric contents(an indicator of acids/bases) which in turn turns to reddish brown to indicate the presence of base in the soap.hence proved..hehe!!...:D
when turmeric is added to soap it works chemically and the colour changes to red...
