- Label one of the test tubes “City Water” and make sure you are only using this test tube for that type of water.
- Collect one sample of water and use the pH strip to test its pH level. Record your findings.
- Repeat step two with nine more samples of city water, for a total of ten city water samples.
- Label the second test tube “Well Water” and make sure you are only using this test tube for that type of water.
- Repeat steps two and three for the well water.
Observation
You can tape the test strips in your notebook as part of your observation. You can also create a graph of your findings to easily display the pH information of both the city and well water.
Result
The results of the experiment depend on the information obtained from the pH strips for both types of water. Did one type of water exhibit a higher or lower pH level than the other? If so, how much of a difference was there? Were the pH levels about the same? Based on the information obtained during your experiment, which type of water do you think is the best for drinking?
