A compound is known to have a free amino group with a pKa of 8.6, and one other ionizible group with a pKa between 5 and 7. To 90mL of a 0.150M solution of this compound at pH 7.80 was added 35 mL of a solution of 0.18 M HCl. The pH changed to 6.40. What is the pKa of the second ionizable group?
For the amino acid alanine, the major species in solution at pH 7 is the zwitterionic form, which has a negatively charged carboxylic acid group and a positively charged amino group. There is a less common neutral form in which neither group is charged. The carboxylic acid group of alanine has a p?apKa of 3.3. The amino group of alanine has a p?apKa of 8.8. Estimate the ratio of the concentration of the neutral amino acid species to the zwitterionic species at pH 7.
