This test uses *turmeric* — a common kitchen spice — as a **natural pH indicator**, which changes color in the presence of a base but not in the presence of an acid. *Materials Needed:* Turmeric powder Water White paper or cotton cloth Detergent powder (base) Lemon juice (acid) Cotton swab or brush --- *Procedure:* 1. *Prepare Turmeric Indicator:* Mix a small amount of turmeric powder with water to form a paste or solution. Use a cotton swab or brush to apply the turmeric paste onto a strip of white paper or cloth. Let it dry completely. 2. *Apply Test Substances:* On one part of the turmeric-stained area, apply a small amount of *lemon juice* using a clean cotton swab. On another part, apply a small amount of *detergent solution* (mix detergent powder with water). --- *Observation:* *Lemon Juice (Acid):* The turmeric-stained area remains **yellow**, indicating an acidic substance. *Detergent Solution (Base):* The turmeric-stained area turns **reddish-brown**, indicating a basic (alkaline) substance. --- *Conclusion:* Turmeric acts as a **natural acid-base indicator**: It stays *yellow* in **acidic solutions**. It turns *reddish-brown* in **basic solutions**. This experiment demonstrates how natural indicators like turmeric can be used to easily test the pH nature of household substances like lemon juice and detergent powder. ‪@allurishikalakshmi5328‬
