Freshman Chemistry Guide 3

This study guide contains over 4 hours and 20 minutes of recorded lecture topics and example problems that follow the material covered in chapter 4 of the textbook Chemistry, The Molecular Nature of Matter and Change by Silberberg. The topics covered include:

Polarity of water molecules and how it helps dissolve ionic compounds and dissociate them into ions.
The types of species present when ionic and covalent compounds dissolve in water and the difference between strong and weak electrolytes.
Using ionic equations to describe the essential nature of aqueous reactions.
What causes aqueous ionic reactions to proceed?
How to predict when a precipitation reaction will occur.
The differences among strong and weak aqueous acids and bases.
The view of aqueous acid-base reactions as proton-transfer processes.
The role of the net movement of electrons in redox processes.
How to use the change in oxidation numbers to identity oxidizing and reducing agents.
Categorizing redox reactions involving elements as combination, decomposition, or displacement types.
