Turmeric Indicator:
Turmeric indicator is a natural pH indicator that is extracted from the turmeric plant. It is commonly used in chemistry experiments to determine whether a substance is acidic, neutral, or basic based on the color change it undergoes when mixed with the indicator.

Working Principle:
- Turmeric contains a compound called curcumin, which changes color depending on the pH of the solution it is mixed with.
- In acidic solutions, turmeric indicator turns red or pink.
- In neutral solutions, it remains yellow.
- In basic solutions, it turns dark red or brown.

Uses:
- Turmeric indicator is often used in educational settings to demonstrate the concept of pH and acidity.
- It can be used to test the pH of household substances such as lemon juice, vinegar, baking soda, and soap.
- Turmeric indicator is also used in traditional medicine and cooking in some cultures.

Advantages:
- Turmeric indicator is natural and non-toxic, making it safe to use in experiments.
- It is easily accessible and can be made at home using turmeric powder and water.
- The color changes of turmeric indicator are easily visible, making it a simple and effective tool for pH testing.

Disadvantages:
- Turmeric indicator may not provide precise pH measurements compared to synthetic indicators.
- The color changes of turmeric indicator can be affected by factors such as temperature and concentration of the solution.
In conclusion, turmeric indicator is a natural and easy-to-use pH indicator that is widely used in chemistry experiments and educational demonstrations. It provides a simple yet effective way to determine the acidity or basicity of a solution based on color changes.
