1. Predict the products (if any) and write the balanced chemical equation, the complete ionic equation, and the net ionic equation (i.e., omitting species that appear on both sides of the complete ionic equation) for each of the following: (a) KBr (aq) + Ba(NO3)2 (aq) (b) NaOH (aq) + HNO3(aq) (c) Adding aqueous silver nitrate to aqueous potassium carbonate yields... (d) Adding aqueous sodium chromate to aqueous magnesium nitrate yields... 2. A sample solution is given to you that may contain any or all of the following ions: Ag, Ba+, and Fe+. In an attempt to determine which cation(s) are present, you add the following solutions. You found that no precipitate formed when either an aqueous solution of NaCl or an aqueous solution of Na2SO4 was added to the sample solution. However, a precipitate did form when you treated the sample solution with a basic solution of NaOH. Which cation or cations are present in the sample? Give your reasoning. (Hint: see Table 4.1 of Zumdahl et al.). 3. Balance the following redox reactions. Identify the oxidizing and reducing agents, and the substances oxidized and reduced. (a) Zn (s) + NO3 (aq) + NH4+ (aq) + Zn+ (aq) in acidic solution. (b) MnO4 (aq) + SO32- (aq) MnO (s) + SO42- (aq) in basic solution. Experimental Procedures
