1. Introduction: The investigation was to see how waste could be made useful. The goals were to get better acquainted with solubility rules for ionic compounds, use these rules to design syntheses of several ionic compounds, and then separate the solid product from the solution. In order to accomplish this, chemicals were mixed with certain acids or bases in order to either safely dispose of them, or to create a useful solid from the liquids. 2. Experimental: 2.1. Apparatus Required: Test Tubes Test Tube Holders Bunsen Burner Matches Test Tube Tongs Filter 2.2. Chemicals Required: 0.1 M BaCl 2 0.1 M HCl 0.1 M NaOH 0.1 M Zn(NO 3 ) 2 0.1 M H 2 SO 4 2.3. Equations Involved: Molecular Reaction- BaCl 2(aq) +H 2 SO 4(aq) BaSO 4(s) +2HCl (aq) Complete Ionic Reaction- Ba +2 (aq) +2Cl - (aq) +2H + (aq) +SO 4 -2 (aq) BaSO 4(s) +2H + (aq) +2Cl - (aq)

Net Ionic Reaction- Ba +2 (aq) + SO 4 -2 (aq) BaSO 4(s) Molecular Reaction- 2HCl (aq) +Zn(NO 3 ) 2(aq) ZnCl 2(aq) +2HNO 3(aq) Complete Ionic Reaction- 2H + (aq) +2Cl - (aq) +Zn +2 (aq) +2NO 3 - (aq) Zn +2 (aq) +2Cl - (aq) +2H + (aq) +2NO 3 - (aq) There is no net ionic equation because no reaction occurred. Molecular Reaction- HCl
