Precipitation Problems

In the following questions, the two solutions are mixed together and a precipitate is formed. The precipitate is allowed to fall out of solution. We will assume that ALL of one of the ions involved in the reaction is completely used up (i.e. none of it still remains in solution).

a) Write the net ionic equation for the precipitate.

b) Calculate the concentration of all remaining ions in solution after the precipitation ends.

1) 10.0 mL of 0.200 M Na2SO4, and 20.0 mL 0.200 M Pb(NO3)2

2) 50.0 mL of 0.500 M AlCl3 and 20.0 mL of 0.800

M Na3PO4,

3) 20.0 mL of 0.250 M NaCl and 30.0 mL of 0.200

M Pb(NO3)2

4) 50.0 mL of 0.300 M AgNO3 and 25.0 mL of 0.480 M Na2SO4

Note: You don't have to answer a) as I understand it, but it would be helpful to have a thorough explanation of b). Thanks!
