Give three differences that might be noted between a titration curve for a strong acid such as hydrochloric acid.
A. No buffer region, steeper slope at equivalence point, higher initial pH
B. Presence of buffer region, gradual slope at equivalence point, lower initial pH
C. No buffer region, gradual slope at equivalence point, lower initial pH
D. Presence of buffer region, steeper slope at equivalence point, higher initial pH
