1. This experiment.
2. The appropriate sections of your textbook.

1. Assume that the silver cation, Ag⁺, forms an insoluble precipitate with all of the anions used in the Precipitation procedure. Write total equation, ionic equation, and net ionic equation for the reaction that occurs when a solution of AgNO₃ is mixed with a solution of the sodium compound of each anion used in the Precipitation procedure.
2. Write the chemical equation representing the reaction between HNO₃ (an acid) and Ba(OH)₂ (a base).
3. In each redox reaction, identify the substance that loses electrons and the substance that gains electrons:
   2K(s) + Cl₂(g) ---> 2KCl(s)
   4Al(s) + 3O₂(g) ---> 2Al₂O₃(s)
   4FeO(s) + O₂(g) ---> 2Fe₂O₃(s)
