Determination of An Unknown Amino Acid From Titration 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 be 183.5. The identity of the unknown amino acid was established to be glutamic acid‚

The 13C NMR spectrum was useful to help finding the structure of the unknown. It showed six different signals in the spectrum. Signal 1 had an observed peak value of 19.242 ppm‚ and its peak calculated value was 19.1 ppm. This signal was first to most upfield and shielded in the spectrum because of the high electron density of carbon. This signal was agreed to a literature value for a CH3 group between 5-30 ppm. Signal 2 was branched to signal 1‚ and had the same value‚ but it was agreed for the
