If strong acid is added to a buffer of pH = 5.10:
a. The pH decreases because the [conjugate base]/[weak acid] decreases.
b. The pH increases because the [conjugate base]/[weak acid] increases.
c. The pH does not change because the [conjugate base]/[weak acid] decreases.
d. The pH increases because the [conjugate base]/[weak acid] decreases.
e. The pH decreases because the [conjugate base]/[weak acid] increases.
