In a prospective buffer system, as the strength of the weak acid decreases (i.e., as the pKa increases), what happens to the strength of the conjugate base?

Select the correct answer below:

a. A weak acid has a weak conjugate base.

b. As the strength of the acid decreases, the conjugate base increases in strength.

c. As the strength of the weak acid decreases the strength of the conjugate base decreases as well.

d. It depends on the acid/base system. Some get stronger, some get weaker.
