By following the ionic compound solubility rules, it is possible to determine which combination of solutions will yield beneficial precipitates. Procedure: To synthesize and subsequently separate our precipitates, specific amounts of initial reactants were measured in a graduated cylinder and combined in a glass tube labeled 1,2, or 3. The first solutions that were combined were 4ml of Ag No 3 (aq) and 2ml of BaCl 2 (aq), and were integrated in tube 1. The second set of solutions that were combined were 2ml of Al(NO 3 ) 3
