TEST on CHAP 4 and Equation-writing (predicting various reaction types and writing net ionic equations). You need to memorize the major solubility rules, the six strong acids, and the strong bases. Review the recent handout on driving forces behind double replacement reactions. Take note of the "magic three." (Naturally, you DO still need to know your ions!) The test will consist of multiple choice, short answer, predicting net ionic reactions from word equations, balancing a redox equation using the oxidation number method, and quantitative predictions when two solutions are mixed. It is designed as a one-bell test, which works well if you have practiced solving the different types of problems so that you know how to be efficient.
Additional practice materials for equation-writing are posted under "Test review" on OneNote-- the answer key to the page handed out earlier (Reaction Prediction 1 and 3) and some fresh exercises and answer key (Reaction Prediction 2 and 4). A hand-written key to exercise 9-3 is also posted there. The more you practice, the better you get! (These resemble the ones we have been doing in class lately.)
