  1. Do precipitation reactions reach a measurable equilibrium?

    Yes they do. 
  2.  

     

  3. What is a solubility product?

    The solubility product, Ksp,  is a measure of this equilibrium.
  4.  

     

  5. What is the common ion effect?

    When a salt (with an ion in common with a precipitate) is added to a solution of the solid precipitate and a decrease in the solubility of the precipitate is observed.
  6.  

     

  7. Calculate the solubility for the following solutions
    1.  

    2. Ag2CO3.  (Ksp = 8.1 x 10-12)

      1.27 x 10-4 M
    3.  

    4. Ag2CO3 in 0.10M AgNO3.

      8.1 x 10-10 M
    5.  

    6. Ag2CO3 in 0.20M Na2CO3

      3.18 x 10-6 M
