A 55.0 ml solution of 0.120 M potassium alaninate ( K* H,NC,H,CO,K) is titrated with 0.120 M HCI. The pK, CH3 values for the amino acid alanine are 2.344 (pKa1) and 9.868 (pK2), which correspond to the carboxylic acid and H2N- -CH- amino groups, respectively. Calculate the pH at the first equivalence point. Potassium Alaninate pH - Calculate the pH at the second equivalence point. pH - A 55.0 ml solution of 0.120 M potassium alaninate ( K* H,NC,H,CO,K) is titrated with 0.120 M HCI.
