2.250 L of gaseous NH3 (Kb = 1.8 x 10-5) at STP. Assuming the volume of the
solution did not change upon addition of the ammonia, calculate:
a. The pH of the solution.
b. The concentrations of all species present in at equilibrium.

2.250 L of gaseous NH3 (Kb = 1.8 x 10-5) at STP. Assuming the volume of the
solution did not change upon the addition of the ammonia, calculate:
a. The pH of the solution.
b. The concentrations of all species present at equilibrium.
Answers: pH = 11, [CH3COOH] = 0.001, [NH3] = 0.05, [CH3COO-] = 0.35
