Question 1

Determine the ammonia concentration of an aqueous solution that has a pH of 11.50. The equation for the dissociation of NH3 (Kb = 1.8 × 10-5) is

NH3(aq) + H2O(l) ⇌ NH4+(aq) + OH-(aq).


◦ 0.55 M
◦ 2.5 M
◦ 5.7 × 10-3 M
◦ 3.2 × 10-3 M

Question 2

How many grams of pyridine are there in 100 mL of an aqueous solution that has a pH of 9.00? The Kb for pyridine is 1.9 × 10-9 and the equation of interest is

C5H5N(aq) + H2O(l) ⇌ C5H5NH+(aq) + OH-(aq).


◦ 0.79 g
◦ 0.053 g
