Yes, this IS a fairly mathematical exam. Dont forget your NON programmable calculator! Chapter 4: Be able to name acids and bases. Ternary acid names are based on the polyatomic ions listed in Table 2.5 or are similar (same group so similar name). What does strong mean and how does that compare to weak? Four strong acids are listed in the book and Ch 4 notes, and remember a lot of Group I & II hydroxides are strong bases. (It's good to know ammonia is a common weak base, and acetic acid is a common weak acid). What does electrolyte mean? All soluble (see later) salts would be considered to be strong electrolytes. Be able to do simple concentration and dilution calculations involving units of molarity (there are other units but we'll use those in CH302). Be able to use the solubility rules (PROVIDED) to determine if something is soluble or if (i.e., what) precipitate(s) will form when two solutions are mixed. Be able to write a total ionic equation or a net ionic equation for a given precipitation reaction, and pick out the spectator ions. Be able to write and balance an acid-base neutralization reaction (Acid + Base gives Salt + Water). Chapter 9: There are a lot of equations.
