Discussion:
1. What observation led you to believe that precipitates formed?
2. How many precipitation reactions did you observe? _________
3) How many different precipitates did you observe?
_________
4) Construct a table summarizing your results similar, which allows combination of
ions that formed precipitates and those that did not.

5) For each different precipitation, write the following:
a) balanced chemical equation
b) complete ionic equation
c) net ionic equation
6) Compare your table from question 4 above to the solubility table located in the
data booklet. Describe any differences or similarities in results.
Conclusion: What did you learn from the experiment?
