The Act of Studying is a Great Activity!
Unit 2 Study Guide
ü Know the difference between strong, weak and nonelectrolytes, and know some examples of each
ü Be able to properly use your Solubility Rules card (or Solubility Table I gave you) to identify soluble
and insoluble compounds, especially when writing net ionic equations for precipitates
ü Know what a metathesis reaction is as well as a single displacement (replacement) reaction
ü Be able to write net ionic equations that involve strong and weak acids and bases
ü Be able to properly assign oxidation numbers using your rules card and/or your Periodic Table
ü Identify whether or not a reaction is a redox reaction and justify your identification using changes in
oxidation numbers
ü Use the half-reaction method to balance a redox reaction
ü Be able to calculate the Molarity of a solution, the amount of solute (in grams) in a solution and the
volume of a solution given solution data
ü Understand the concept of “ion concentration” and how the concentration of ions in a solution can be
different from the concentration of the solution itself based on the ion ratio in the compound; also,
perform calculations involving this concept
ü Be able to draw a picture showing the dissolving of an ionic compound in water
ü Be able to do a proper calculation for the dilution of a solution (MV=MV)
ü Know the proper laboratory technique for making a solution of a specific Molarity
ü Be able to calculate the concentration of a solution made from mixing 2 solutions together of the same
type (total moles divided by total volume J)
ü Know the proper laboratory techniques involved with gravimetric analysis
ü Be able to perform proper gravimetric analysis calculations like in your notes packet and in the lab
ü Do a titration calculation like you did in lab involving finding the percentage by mass of acetic acid in
vinegar by titrating it with a strong base
