I mix the following things into a SINGLE 1 L beaker:

150 mL of 0.100 M Na2CO3

50.0 mL of 0.050 M BaCl2

100.0 mL of 0.025 M Cu(NO3)2

100.0 mL of 0.125 M Ca(NO3)2

50.0 mL of 0.100 M NaOH

After the “soup” is all done “cooking”...er...after equilibrium has been established, tell me the following:

1. What (if any) are all of the precipitates?

2. What is the mass of each precipitate?  (If any)

3. What is the concentration (Molarity) of each chemical species that is still in solution?
