< D T PRE-LABORATORY ASSIGNMENT C. Q Ų The pre-laboratory assignment must be completed before beginning the laboratory experiment. a. Qualitative Analysis: 14 Solutions 4 52 + : 1. Read the lab manual and finish the following steps: a. Prepare a list of the cations involved in this experiment that could not be present in a solution if carbonate ions, CO32-, were also present in that solution. b. Some cations listed in this experiment are not stable in water. They may react with OH-in water to form H* and an insoluble hydroxide. How would you keep such an insoluble hydroxide from forming? For the 14 unknown solutions with possible ions as given in this experiment, describe a logical scheme for identifying each anion. Draw a flowchart for the identification if possible. 2. Review relevant class materials and answer the following questions: You are given a solution that may be either NaCl(aq) or Na₂CO3(aq). Present a scheme to find which substance was present in the solution. b. Complete and balance the following equations and explain your results. BaCl₂(aq) + H₂SO4 (aq) → AgNO3(aq) + Cl(aq) → ···.
