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.
turmeric dissolved in water is treated with citric acid(lemon or juice of any citrus fruit) red color is formed due to the reaction of phenol(in turmeric) with trioic acid present in citric acid

Soap water can break down the turmeric particles due to its surfactant properties, resulting in the dispersion of the yellow color of turmeric in the solution. This happens because soap molecules can interact with the turmeric molecules and prevent them from clumping together.
Adding sugar to a turmeric solution will not have a significant impact on the properties of the solution. The sugar will dissolve in the solution, but it will not alter the color or smell of the turmeric. Turmeric will still retain its characteristic properties in the presence of sugar.
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.
