Question
1. HCN is a weak acid (Ka=6.20x10-10) , so
the salt, KCN , acts as a weak base. What is
the pH of a solution that is 0.0570 M in KCN
at 25 °C?
2. A solution was prepared with 0.464 mol
of pyridinium fluoride (C5H5NHF) and
enough water to make a 1.00 L. Pyridine
(C5H5N) has a Kb=1.70×10-9 and HF has a
Ka=6.30x10-4.
