Aim: To separate substances by the properties of interpenetrateing and crystallisation. Apparatus and Chemicals: - balance. - 100mL-beaker (2). - Filter funnel stand and drool funnel. - Bunsen, Tripod and gauze mat. - Watch glass. - Glass rod. - 100mL Beaker (2) - 25mL graduated cylinder. - Filter paper - boiling Chips - Matches - NaCl/C categorisation (sodium chloride/ charcoal-grey 4g.) - NaCl/CuCl^2 potpourri (Sodium chloride/ papal bull (II) chloride alloy, 8g.) - C^2H^5OH (Ethanol, Approx. 25L.) - Distilled wet Method: bump A 1. Place 4g of the NaCl/C categorisation into a 100mL beaker. convey approximately 15mL of distilled water. Stir for about 2 minutes. 2. Set up a filter funnel. Into it place the filter paper, folded into a fluted pattern, and stand. [As in figure 1.1] Pour the whole mixture into the funnel and clear the filtrate in a 100mL beaker. 3. airstream the residue into the beaker with a raise 5mL of water and pour into the funnel. 4. leave one o r 2 boiling chips to the filtrate. Heat this with a Bunsen burner using a preferably high flame. boiling point gently to reduce volume. As soon as almost crystals begin to appear flexure rancid and allow to cool. Part B: 1. Place $ o the NaCl/CuCl^2 mixture in a 100mL beaker and dissolve in about 15mL of distilled water. 2.
Warm the source with a Bunsen burner using a quite blue flame until crystals begin to appear in the result. sell off and remove the Bunsen. Allow the solution to cool. 3.Filter the solid organize and washout with about 5mL of C^2H^5OH. Part C: 1.Place 4g of NaCl/CuCl^2 mixture in a 100 mL beaker and add about 15mL of C^2H^5OH. 2.! Stir the solution for about 2 minutes and filter off the un-dissolved solids. wash drawing the solid with about 5mL of C^2H^5OH. 3.Plce about...
