Question Completion Status: QUESTION 28 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 QUESTION 29 Which of the following cannot be a buffer solution? Each component is at 0.050 M concentration. OHCI/CI OH-C₂H302/ C2H30₂ O NH4+/NH3 O HNO₂/NO₂ QUESTION 30 Below is a titration curve of a sample of monoprotic acid (HA) by NaOH.
