Aspartic acid has a side chain bearing a carboxylic acid group; its pKą is ~4. The alpha-carboxylic and alpha-amino groups have pką values similar to those of alanine, - 2 and ~9, respectively. Determine the net charge on an aspartic acid molecule at the following pH values (match each pH to the best choice).
