Estimating the Effects of Acid Rain Joe Gotschall 2470911 Section 10 Purpose: Titrate natural water samples with sulfuric acid, using a pH meter or chemical indicators. Calculate the alkalinity of the water samples. Classify the water sources in terms of alkalinity according to Environmental Protection Agency standards. Outline 1. Sampling a water source a. Get water from lab asst. 2. Determining the Acidity using a pH meter a. Calibrate the pH meter b. Determine the Initial pH of the sample c. Titrate the sample to determine volume A d. Titrate the sample to determine volume B 3. Determine the Acidity of the sample with Chemical Indicators a. Determine the Initial pH of the sample

Unformatted text preview: b. Titrate the sample to determine volume A c. Titrate the sample to determine volume B Discussion We used to different methods of calculating pH of a substance, using chemical indicators and a pH meter and tried to see how close we could get to the measurement of both. In the end if they were both measured correctly we should have the same alkalinities for both. Our alkalinities were off by 5.2 mg L -1. This could be because the chemical indicators were not as accurate or we titrated to long perhaps, but overall I think we came pretty close and am overall happy with our outcome....
