Identifying Three Liquids Using Turmeric Indicator

Turmeric indicator is a commonly used natural indicator that changes color in the presence of acidic or basic solutions. It turns yellow in an acidic solution and reddish-brown in a basic solution. In this scenario, we have three liquids - hydrochloric acid, sodium hydroxide, and a sugar solution, and we need to identify them using turmeric indicator. Here is how we can do it:

Materials Required:

- Three test tubes
- Turmeric indicator
- Dropper
- Hydrochloric acid
- Sodium hydroxide
- Sugar solution

Procedure:

1. Label the test tubes as A, B, and C.
2. Add a few drops of turmeric indicator to each test tube using a dropper.
3. Add a small amount of hydrochloric acid to test tube A and observe the color change. If it turns yellow, it is an acidic solution.
4. Add a small amount of sodium hydroxide to test tube B and observe the color change. If it turns reddish-brown, it is a basic solution.
5. Add a small amount of sugar solution to test tube C and observe the color change. If it remains yellow, it is neutral or slightly acidic.

Observations:

- Test tube A turned yellow, indicating that it is an acidic solution.
- Test tube B turned reddish-brown, indicating that it is a basic solution.
- Test tube C remained yellow, indicating that it is neutral or slightly acidic.

Conclusion:

Based on the observations, we can conclude that:

- Test tube A contains hydrochloric acid, which is an acidic solution.
- Test tube B contains sodium hydroxide, which is a basic solution.
- Test tube C contains a sugar solution, which is neutral or slightly acidic.

In this way, we can identify the given liquids using turmeric indicator without the need for expensive equipment or chemicals. However, it is important to handle the chemicals with care and follow the safety guidelines to avoid any accidents.
