Lowell Honors Chemistry
Test Study Guide: Chapter 4
Redox and Precipitation Reactions
[Note: No calculators allowed. You will be provided with a copy of the periodic table. The test is all short answer / writing chemical equations.]
KNOW THE FOLLOWING CONCEPTS:
o Difference between oxidation and reduction
o Difference between oxidizing agent and reducing agent
o How to determine the oxidation number of a particular element
o The electrodes where oxidation and reduction occur
o The direction electrons travel between electrodes
o The difference between a molecular equation, ionic equation, and net ionic equation
o The role of precipitates and spectator ions in precipitation reactions
o Know the solubility rules and exceptions from your handout
o Know the Activity Series of Metals from your textbook
BE ABLE TO WRITE BALANCED CHEMICAL EQUATIONS INVOLVING:
o redox reactions [molecular equation to ionic equation to net ionic equation]
o precipitation reactions (know the solubility rules)
o single-replacement redox reactions (know the activity series of metals)
