Turmeric, which contains a natural pH indicator called curcumin, turns from yellow to red in the presence of bases. This color change is often used as a simple and visual way to test for the presence of bases, such as sodium hydroxide (lye) or baking soda (sodium bicarbonate), in a solution. The red coloration occurs due to a chemical reaction between curcumin and the base, resulting in the formation of a red compound. This property makes turmeric a useful tool in various chemistry experiments and in cooking to detect the alkaline nature of certain ingredients or substances.
