The concentration of phosphoric acid "A" is about twice as concentrated as phosphoric acid "B". Compare the titration curve of phosphoric acid "A" and "B. When comparing both titration curves, briefly point out the obvious similarities and differences between the two? What is causing the similarities and differences? Explain in terms of buffering regions and buffer capacity.
