What volume (in milliliters) of 0.120 M NaOH should be added to a 0.125 L solution of 0.0250 M glycine hydrochloride (pKa1 = 2.350, pKa2 = 9.778) to adjust the pH to 2.96?

A 65.0 mL solution of 0.161 M potassium alaninate (H2NC2H5CO2K) is titrated with 0.161 M HCl. The pKa values for the amino acid alanine are 2.344 (pKa1) and 9.868 (pKa2), which correspond to the carboxylic acid and amino groups, respectively.a) Calculate the pH at the first equivalence point.b) Calculate the pH at the second equivalence point.
