Check all that is true for a buffer solution. The pH of a buffer solution can be determined by the Henderson-Hasselbalch equation When the acid and base components of the buffer solution is present in equal amount, pH = pka When a strong acid is added to a buffer solution, the acid component of the buffer solution will decrease in concentration. A buffer solution is resistant to changes in its pH A buffer solution contains a weak(<100% ionization) conjugate acid/base pair
