Abstract Experiment 11 used a titration curve to determine the identity of an unknown amino acid. The initial pH of the solution was 1.96, and the pKa's found experimentally were 2.0, 4.0, and 9.85. The accepted pKa values were found to be 2.10, 4.07, and 9.47. The molecular weight was calculated to be 176.3 while the accepted value was found to...

The Chesapeake Bay is America's largest estuary and one of the world's most productive. The Bay is home to over 2,700 species. It draws water from over 150 rivers, streams, and creaks, receiving roughly 70,000 cubic feet of water every second. That water reflects the surrounding land use activities of the District of Columbia, parts of New York, Pe...
