A solution of 0.148 M aspartic acid, the charge neutral form of the amino acid, is titrated with 0.0370 M NaOH. The pK₂ values for aspartic acid are 1.990, 3.900, and 10.002, corresponding to the a-carboxylic acid group, the B- carboxylic acid group, and the amino group, respectively. Calculate the pH at the first equivalence point of this titration. pH = NH₂ HC-CH₂-C-OH B a C=O 0 Aspartic Acid
