Question

what colour will be formed when we mix rust and turmeric powder?​

Answer 1

Answer:

Turmeric contains curcumin, a chemical that turns red with bases and yellow with acids in water. Baking soda is a base, so when students add turmeric, the curcumin in it turns red. The carbon dioxide produced in the reaction mixes with water to make an acid. So in the course of the reaction, the solution turns yellow.
