1. In an experiment, you are given a set of seven colorless aqueous solutions in glass vials labeled with numbers. The unknowns are barium chloride, sodium sulfate, potassium iodide, lead (II) nitrate, sodium carbonate, sodium sulfide, and ammonium chloride. Write the formula for each of the unknowns.
2. Which unknowns would give a white precipitate with sodium sulfate solution? Write molecular and net ionic equations for all of them. Be sure to include the phases of each reactant and product. (i.e. (s), (l), (g), or (aq)). Remember that your equations should be balanced!
3. Suppose you had added silver nitrate solution to all of the test tubes, which of the unknowns would have reacted? Write molecular and net ionic equations for all of them. Be sure to include the phases of each reactant and product. (i.e. (s), (l), (g), or (aq)). Remember that your equations should be balanced!
4. Suppose you had added a magnesium strip to all of the test tubes, which of the unknowns would have reacted? Write balanced chemical equations for all of them. Remember that your equations should be balanced!
