Measuring the pH Levels of Distilled, Tap, and Acidic Water: An Experiment

This experiment investigates the pH levels of three types of water: distilled, tap, and acidic. Using a pH sensor and various accessories, we measured the acidity of each solution. The pH scale ranges from 0 to 14, with levels below 7 indicating acidity and above 7 indicating basicity. The results showed that distilled water had a pH around 7, tap water ranged from 7.3 to 7.4, indicating slight basicity, while acidic water measured between 2.16 and 2.22, demonstrating high acidity. This highlights the varying acidity levels of common water types.

  1. Description of experiment • The tools and materials are: • Fourier accessories • 3 beakers • netbook • distilled water • acidic water • tap water • The objective consists in finding the PH of • acidic water • distilled water • tap water • The pH measures the acidity of a solution. • The pH scale ranges: • from 0 to 14; • from 0 to 7 for acid ; • from 7 to 14 for basic ; • 7 is the value of neutrality .

  2. Graph PH of distilled water. This graph represents the ph of distilled water. The value of pH varies from 7 to 7.4: the distilled water is basic.

  3. Graph PH of water tap. This graph represents the ph of tap water. The value of pH varies from 7.3 to 7.4: the distilled water is basic.

  4. Graph PH of acid water. This graph represents the ph of acid water. The value of pH varies from 2.22 to 2.16: the distilled water is acid.

  5. Conclusion The distilled water has the ph of 7, the tap water has ph between 7 to 8 and acid water has ph 2. The distilled and acid water decrease in time, while the ph of tap water increases . Note Ph sensor We have used the acid water solution instead of rainwater because it was impossible to collect real samples of rainwater.
