For a series of weak acids, the increase in pKa means that the conjugate bases become more stable.
<h3>What is pKa?</h3>
The term pKa refers to the negative logarithm of the acid dissociation constant. This is a constant that shows the extent to which an acid is dissociated in solution.
As the pKa of a series of weak acids increases, the conjugate bases become more stable.
