Work in groups on these problems. You should try to answer the questions without referring to your textbook. If you get stuck, try asking another group for help.

1. Complete the equilibrium and write the \(K_{sp}\) expression for each of the following:

  1. \(AgCl_{(s)}\)  
  2. \(Ag_2CO_{3\,(s)}\)
  3. \(Sr_3(PO_4)_{2\,(s)}\)    

 

2.  Given the \(K_{sp}\) = 3.0 x 10-14 for \(MnS\), determine if a precipitate will occur from mixing 0.8 L of 0.002 M \(Na_2S\) solution with 0.5 L 0.012 M \(Mn(NO_3)_2\) solution.

 

3. Determine the molar solubility of \(CuS\). \(K_{sp}\) = 6.0 x 10-37

 

4. Determine the \(K_{sp}\) for \(PbI_2\) if the molar solubility is 1.52 x 10-3 M.

 

5. Calculate the solubility (g/L) of \(AgI\) in 0.06 M \(AgNO_3\).   \(K_{sp}\) = 8.3 x 10-17

 

6. Determine if the following compounds are soluble (S) or insoluble (I)

\(Al(OH)_3\)   _______ 

\(CuNO_3\)  _______ 

\((NH_4)_3PO_4\) _______

\(CdS\) _______  

\(AgI\) _______
