Question 1

What is not a correct expression for the weak acid HA?
◦ pKa = 14 - pKb
◦ pKa = logKa
◦ Ka = [H3O+][A-]/[HA]
◦ pKa = pH - log{[A-]/[HA]}

Question 2

Which is the best acid to use in the preparation of a buffer with pH = 3.3?
◦ HIO3 (Ka = 1.7 × 10-1)
◦ HNO2 (Ka = 4.5 × 10-4)
◦ HNO3
◦ HOI (Ka = 2.0 × 10-11)
