Identifying Three Liquids using Turmeric Indicator
Identifying hydrochloric acid, sodium hydroxide, and a sugar solution can be done using turmeric indicator. Turmeric indicator is a natural pH indicator that changes color in the presence of acidic or basic solutions.

Testing Procedure
1. Hydrochloric Acid: Add a few drops of turmeric indicator to the liquid. If the color changes to red or pink, it indicates the presence of an acid. In this case, hydrochloric acid will turn the turmeric indicator red due to its acidic nature.
2. Sodium Hydroxide: In another test tube, add turmeric indicator to the second liquid. If the color changes to dark yellow or brown, it indicates the presence of a base. Sodium hydroxide, being a strong base, will turn the turmeric indicator dark yellow or brown.
3. Sugar Solution: Finally, test the third liquid by adding turmeric indicator to it. If there is no significant color change and the solution remains yellow, it indicates a neutral pH. Sugar solution does not significantly affect the color of turmeric indicator as it is neither acidic nor basic.

Conclusion
By observing the color changes in the turmeric indicator when added to the three liquids, you can easily identify hydrochloric acid, sodium hydroxide, and a sugar solution based on their acidic, basic, or neutral properties. This simple experiment demonstrates the effectiveness of turmeric indicator as a pH indicator for differentiating between acids, bases, and neutral substances.
