Question 1

Which of the following mixtures would result in a buffered solution when 1.0 L of each of the two solutions are mixed.
◦ 0.2 M HNO3 and 0.4 M NaF
◦ 0.2 M HNO3 and 0.4 M NaOH
◦ 0.2 M HNO3 and 0.4 M HF
◦ 0.2 M HNO3 and 0.2 M NaNO3

Question 2

What is the Henderson-Hasselbalch equation for the acidic buffer HA/A-?
◦ pH = 14 - pOH
◦ pH = pKa + log{[A-]/[HA]}
◦ pH = pKa - log{[A-]/[HA]}
◦ pH = -log[H3O+]
