How does the pKa of a buffering agent relate to its effectiveness at a particular pH?
A buffer is most effective when the pKa is much higher than the pH.
A buffer is most effective when the pKa is equal to or close to the pH.
A buffer is most effective when the pKa is much lower than the pH.
The pKa does not affect the buffer’s effectiveness at a particular pH.
