1A solution of 0.235 M aspartic acid, the charge neutral form of the amino acid, is titrated with 0.118 M NaOH . The p K a values for aspartic acid are 1.990 , 3.900 , and 10.002 , corresponding to the α-carboxylic acid group, the β-carboxylic acid group, and the amino group, respectively. Calculate the pH at the first equivalence point of this titration.

Consider a 0.211 L solution of the amino acid aspartic acid (0.631 M), which has an alpha carboxylic acid group (pka = 2.10), an alpha amine group (pka = 9.82), and a carboxylic acid group in the side chain (pka = 3.86). If the titration is started at a very low pH, how many liters of 2.25 M NaOH would you need to add to reach the isoelectric point of the amino acid? Give your answer...
