What is a weak base?
Think about how it behaves in water compared to strong bases.
Which base is a common example of a weak base?
Consider everyday items containing ammonia.
What defines a weak base?
Consider the differences between weak and strong bases.
True or False: Ammonia is a strong base.
Review the definitions of strong and weak bases.
A solution of a weak base B has a Kb = 1.0 x 10^-5. If the initial concentration of B is 0.1 M, calculate the concentration of OH- at equilibrium.
Set up an ICE table and don't forget to determine the equilibrium concentrations correctly.
A buffer solution contains 0.1 M ammonia and 0.1 M ammonium chloride. Calculate the pH of the solution given Kb for ammonia is 1.8 x 10^-5.
Remember to convert Kb to pKb and apply the Henderson-Hasselbalch equation effectively.
