On that last one, I can understand why you might prefer the first one, but because the " A " means " Esters of aminobenzoic acid " and " B " means " Amides ", I believe a numerical sort is far more useful than a alphabetical one.

Let's say I have an amino acid ( not a biological one-- say it's 4-aminobenzoic acid with two pKa's : 2.50 at the + 1 state and 4.87 in the + 0 state . . . let's say the concentration is 0.1M . How do I calculate what the pH of the solution will be?
