Question: For an amino acid such as alanine, the major species in solution at pH 7 is the zwitterionic form. Assume a pKa value of 8 for the amino group and a pKa value of 3 for the carboxylic acid. Estimate the ratio of the concentration of the neutral amino acid species (with the carboxylic acid protonated and the amino group neutral) to that of the zwitterionic species at pH 7.
