In the titration of a weak acid of known concentratin with a standard solution of a strong base, a ph water was used to follow the progress of the titration. Which of the following is true of this experiment.
A. The pH at the equivalence point depends on the indicator used
B. The graph of pH versus volume of base added rises gradually at first and then much more rapidally.
C. The graph of pH versus volume of base added shows no sharp rise.
D. The `[H^(+)]` at the equivalence point equals the ionization constant of the acid
