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....
