CHAPTER 4 LEARNING OBJECTIVES
To satisfy the minimum requirements for this course, you should be able to:
Apply your understanding of the properties of aqueous solutions to:
identify the solvent and solute(s) in a solution (pg.119, SG69)
predict whether a substance is a strong electrolyte, weak electrolyte, or nonelectrolyte (pg. 120, Table
4.1, prob 4.10)
write balanced chemical equations for the dissolving of molecular compounds, ionic compounds, or
acids in water (pg. 120, 127, SG71, prob 4.22)
Write molecular, ionic, and net ionic equations for precipitation reactions (pg 124, SG70), acid-base
reactions (pg. 128), and oxidation-reduction (redox) reactions (pg. 133, SG73), and identify spectator ions (pg.
124) prob 4.34.
Recognize precipitation reactions and use solubility rules (Table 4.2) to predict when a precipitation
reaction is likely to occur (pg. 123, Example 4.1, SG70)
Recognize acid-base reactions and be able to:
explain the differences between the Arrhenius and Bronsted definitions of acids and bases (pg. 127,
SG71, prob 4.32)
explain the differences between strong and weak acids and between strong and weak bases (pg. 128,
Table 4.3)
provide the names and formulas of common acids and bases (see general chemistry pro-knowledge)
and classify acids as either monoprotic, diprotic, or triprotic (pg. 128, SG72)
Recognize oxidation reduction (redox) reactions and be able to:
determine the oxidation numbers of atoms involved in a redox reaction (pg. 135, SG74) prob 4.46
identify the compounds being oxidized and reduced and the oxidizing and
reducing agents (pg. 134, SG73) prob 4.44
recognize the following types of redox reactions:
combination (pg. 137), decomposition (pg. 139), combustion (pg. 141), displacement (pg. 139-142), and
disproportionation (pg. 143)
use the activity series to predict whether a displacement reaction will occur (pg. 141, Figure 4.16, prob 4.54)
Perform the following calculations involving concentration:
calculate the molarity, solution volume , or number of moles of solute given any
two of these quantities (pg. 147-148) prob 4.66,68 SG75
dilution calculations (pg. 149) SG65 prob 4.70
titration calculations for both acid-base (pg. 153) and redox reactions (pg. 155). Prob 4.90 SG 76-77
