 |
|
Hi,
We recently did the titration of amino acids, and covered such things as the zwitter ion etc., and I understand these concepts, and I can identify them in a graph, but..
I was given theoretical solution of alanine, (100% protonated), and told to calculate the pH at various steps during titration. At the very beginning, I suppose I simply consider COOH as an acid, but as I approach the zwitter ion state, don't I need to consider both acids? How do I calculate that?
thanks in advance
