Victor  PURPOSE: The purpose of this lab is to determine which aqueous solution is contained in each  tube   through   experimentation   with   mixing   solutions   and   making   qualitative  observations and to determine the net ionic equation for each reaction. EQUIPMENT: 12 test tubes 12 aqueous solutions Spot plate  12 eyedroppers REAGENTS: Cup G (Solution corresponds to container number) 0.2 M potassium chromate 7 1.0 M aluminum chloride 8 1.0 M sodium carbonate 2 6.0 M hydrochloric acid 5 6.0M sodium hydroxide 11 0.1 M silver nitrate 4 6.0 M ammonia 3 0.1 M lead(II)nitrate 10 0.1 M iron(III)nitrate 2 1.0 M sodium acetate 9 0.1 M copper(II)sulfate 1 0.1 M nickel(II)chloride 6

PROCEDURE: 1. Do extensive research on ions, colors, and precipitates of reactions 2. Mix two drops of the solution from one test tube in a spot plate with 2 drops of the next  solution.  3. Make observations in data table 4. Repeat   for   every   possible   combination.   Use   data   to   conclude   what   the   mystery  solutions are. DATA: (ATTACHED EXCEP CHART) CALCULATIONS: 1. Pb(NO 3 ) 2  + Na 2 CO 3      PbCO 3  + 2NaNO 3 Net Ionic: CO 3 -2  + Pb +2         PbCO 3   2. 2HCl + Pb(NO 3 ) 2    2HNO 3  + PbCl 2 Net Ionic: 2Cl + Pb +2        PbCl 2 3. Pb(NO 3 ) 2  + CuSO 4     PbSO + Cu(NO 3 ) 2 Net Ionic: SO 4 -2  + Pb +2        PbSO 4 4. K 2 CrO 4  + Pb(NO 3 ) 2      PbCrO + 2KNO 3 Net Ionic: CrO 4 -2  + Pb +2        PbCrO 4 5. 2AlCl 3  + 3Pb(NO 3 ) 2        2Al(NO 3 ) 3  + 3PbCl 2 Net Ionic: 6Cl + 3Pb +2      3PbCl 2 6. 2NaOH + Pb(NO 3 ) 2      2NaNO 3  + Pb(OH) 2 Net Ionic: 2OH + Pb +2         Pb(OH) 2 7. 2HCl + Na 2 CO 3      2NaCl + H 2 CO 3
