Q1
A weak acid (pka = 6.3) is dissolved in solution with a final pH = 5.7. At this pH, some of the acid dissociates
into its conjugate base (A-), while some stays in the protonated form (HA). Using the Henderson Hasselbach
equation, determine the % of the molecules that are HA vs A-.
20% is HA, 80% is A-
40% is HA, 60% is A-
60% is HA, 40% is A-
80% is HA, 20% is A-
Question 4
Generally speaking, which of the following types of IMF can be the strongest (have the greatest energy)?
Ion-ion interactions
Hydrogen bonding
Aromatic interactions
Van der Waals interactions
