A solution contains 0.010 M each Cu(NO3)2 and Bi(NO3)3. An equal portion of 12 M NH3 is added to the solution.
What is the initial concentration of OH- (in M) once the two solutions have been mixed together, but prior to any reactions occurring? The Kb for NH3 = 1.8 x 10-5.
Once all reactions have completed, what is the equilibrium concentration (in M) of Cu2+? Assume that the concentrations of NH3 and OH- are buffered and cannot change from their initial values. The Kf for Cu(NH3)4 2+ = 1.1 x 1013.
Once all reactions have completed, what is the equilibrium concentration (in M) of Cu(NH3)4 2+ ? Assume that the concentrations of NH3 and OH- are buffered and cannot change from their initial values.
Once all reactions have completed, what is the equilibrium concentration (in M) of Bi3+? Assume that the concentrations of NH3 and OH- are buffered and cannot change from their initial values. The Ksp for Bi(OH)3 = 3.2 x 10-40.
