Precipitation Reaction Mini-Lab
Purpose: To predict precipitates using solubility rules and the chemicals available as well as to
write complete molecular, complete ionic and net ionic equations for precipitation reactions.
There are 15 solutions on the table in front of you. Using your solubility rules, determine 7
combinations that SHOULD result in a precipitate formed. Jot those 7 combinations in your
notebook.
Using a blank piece of paper, create a reaction spot for each of your combinations (this was
demonstrated in class). Cover your piece of paper with a transparency sheet. Place 2 drops of
each chemical in your reaction spot. If necessary, use a toothpick to mix. Record your
observations in your lab notebook and take a picture of your reaction sheet.
If any of your combinations did not react, create another combination that does react to bring
your total reacted combinations to 7.
For every combination that reacted, write a balanced molecular equation, a complete ionic
equation, and a net ionic equation in your lab notebook.
