What information can be obtained from a titration curve of an acid, the curve of which showed three (3) inflection points. A. The acid is a weak polyprotic acid of the form H3A B. Each inflection point denotes the negative logarithm of the dissociation constant of each ionizable proton C. The weak acid can act as a buffer with a wide range of pH from the first inflection point to the last point with the highest pKa value. D. Both A and B E. All of these
