Step 1
The equilibrium constant for this reaction is Kb = [NH4+][OH-]/[NH3]. Since we know the concentration of ammonia is 0.1M, we can assume that the concentration of NH4+ and OH- are negligible compared to 0.1M. Therefore, we can simplify the equation to Kb = Show more…

a) Calculate the pH of a solution prepared by dissolving 0.75 moles of NH3 and 0.25 moles of NH4Cl in water sufficient to yield 1.00 L of solution. The Kb for ammonia is 1.8 x10-4. b) Now calculate the pH of the solution after adding 0.075 moles of NaOH.
