One experiment that can be done to find the pH level using universal indicator is as follows:
1. Prepare a series of test tubes or small containers with different solutions of known pH levels. These solutions can include distilled water (pH 7), lemon juice (pH 2), vinegar (pH 3), baking soda solution (pH 8), and ammonia solution (pH 11).
2. Add a few drops of universal indicator to each of the solutions and observe the color change. Universal indicator changes color depending on the pH level of the solution, with red indicating acidic pH, green indicating neutral pH, and blue/purple indicating alkaline pH.
3. Compare the color of the solutions with the color chart provided with the universal indicator to determine the approximate pH level of each solution.
4. Once you have determined the pH levels of the known solutions, you can then test an unknown solution by adding a few drops of universal indicator and comparing the color change to the color chart to determine its pH level.
5. Record your observations and results in a table or chart to analyze and compare the pH levels of the different solutions.
This experiment can be a fun and educational way to learn about pH levels and how universal indicator can be used to determine the acidity or alkalinity of a solution.
