BIOC 460 General Chemistry Review
... Grisham, Biochemistry, 3rd ed., 2004. For a polyprotic acid (more than one acidic group, so more than one pKa on titration curve), it takes 1 equivalent of OH– to titrate each acidic group, so a triprotic acid like phosphoric acid requires 3 equivalents. The pKa values are pH values at each half equ ...
