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)
