Experiment 6


Precipitation Reactions

1.  What is a precipitation reaction?

2.  What is a precipitate?

3.  Why would you have a precipitate?  Look at solubility rules for this reaction.

4.  Look at net ionic equations and write one for this reaction.  The product left is the insoluble.

5.  What does a net ionic equation tell you?

6.  What is a limiting reactant?  What does it mean and do?

7.  What are you using and what safety precautions should be used?  (Hint:  AgNO3 stains the skins and will not come off for a while)



Experiment 7


1.  What is an acid and a base?

2.  What is a titration?  What is it used for/purpose?
