Chapter 18 Acids and Bases Test Review
Remember to show your work and units. You can take the Chapter 18 Acids and Bases Test in pairs
and both of you may bring a 3xS card (front and back) to use as notes. The only thing I will give you
will be a Periodic Table. If you choose to take the test in pairs you will complete the same test and
receive the same score.
Questions #1-10 are TRUE or FALSE.Write True or False on the blank next to each question.
