Unformatted text preview: Chem 11 Exp. #4 Solubility and Precipitation Pre-laboratory Assignment 1. Review in Zumdahl, Precipitation Reactions , pages 99-104. 2. Review in Zumdahl, Describing Reactions in Solution , pages 104-105. 3. Define the following terms: soluble substance, precipitation, net ionic equation, solubility rules. 4. Calculate how many grams of FeSO 4 . 7 H 2 O (MW = 278.02 g/mol) will be needed to prepare 1 mL of a 0.2 M FeSO 4 solution? Introduction In this laboratory experiment, aqueous solutions containing ionic compounds will be studied. An aqueous solution containing dissociated ions will be mixed with another solution containing dissociated ions. (The positive ions are referred to as cations and negative ions are referred to as anions, see the example of the Ionic Equation shown in Figure 1.) The products from these reactions will be examined (see Figure 1). If the product from the reaction is soluble, the reaction mixture will be clear. If the product from the reaction is insoluble, a precipitate will be generated in the reaction mixture. From the data obtained from each reaction, a set of solubility rules will begenerated in the reaction mixture....
