One experiment that can be done to find pH 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 range from very acidic (pH 1-3) to very basic (pH 11-14).
2. Add a few drops of universal indicator to each of the test tubes or containers. Universal indicator is a mixture of several different indicators that change color at different pH levels, allowing for a broad range of pH values to be measured.
3. Observe the color change in each solution and compare it to a universal indicator color chart. The color of the solution will correspond to a specific pH level on the chart.
4. Use the color chart to determine the pH of each solution based on the color change observed in the universal indicator.
5. Record the pH values of each solution and compare them to the known pH levels to verify the accuracy of the universal indicator in determining pH.
This experiment can be repeated with different solutions of unknown pH levels to practice using universal indicator to determine the acidity or basicity of a solution.
