Le Chatelier InvestigationLucianna and EmilyReaction:Fe3+(aq)+SCN-(aq)FeSCN2+(aq)Background information:Hydrogen phosphate ion has a similar solubility to the phosphate ionIron(III) ions are amber coloredThiocyanate ions are colourlessIron (III) thiocyanate ions are dark red colouredAssume room is 22oCEquipment:-5 x test tubes-beaker-test tube rack-funnel-25mL graduated cylinder-grease pencil-scoopula-Bunsen burner or hot plate-retort stand-appropriate clampsChemicals:-10.0 mL of thiocyanate solution (0.002 M)-10.0 mL of distilled water-2 drops ( ~ 1 mL) iron (III) nitrate solution (0.4 M)-a few thiocyanate crystals-a few iron (III) nitrate crystals-a few sodium hydrogen phosphate crystals
Procedure:1.Place 10.0 mL of thiocyanate solution in 100 mL beaker2.Place 10.0 mL of distilled water in same 100 mL beaker as step 13.Add 2 drops of iron (III) nitrate solution to same beaker as step 14.Mix contents of beaker5.Place ~4.0 mL of solution from the beaker into each of the 5 test tubes6.With grease pencil label each test tube 1 through 57.Record color of solution in each test tube8.
