Aim: To separate substances by the properties of interpenetrateing and crystallisation. Apparatus and Chemicals: - balance. - 100mL-beaker (2). - Filter funnel stand and diffuse funnel. - Bunsen, Tripod and gauze mat. - Watch glass. - Glass rod. - 100mL Beaker (2) - 25mL calibrated cylinder. - Filter paper - boiling Chips - Matches - NaCl/C categorisation (sodium chloride/ wood coal 4g.) - NaCl/CuCl^2 confection (Sodium chloride/ papal bull (II) chloride diverseness, 8g.) - C^2H^5OH (Ethanol, Approx. 25L.) - Distilled irrigate Method: erupt A 1. Place 4g of the NaCl/C concoction 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. subspecies the residue into the beaker with a raise 5mL of water and pour into the funnel. 4. ca st up one or 2 boiling chips to the filtrate. Heat this with a Bunsen burner using a preferably unconsecrated flame. rile gently to reduce volume. As soon as just about crystals begin to appear flexure dark 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 cornerstone with a Bunsen burner using a quite blue flame until crystals begin to appear in the source. sell off and remove the Bunsen. Allow the solution to cool. 3.Filter the solid organize and drizzle with about 5mL of C^2H^5OH. Part C: 1.Place 4g of NaCl/CuCl^2 mixture in a 100mL beaker and add about 15mL of C^2! H^5OH. 2.Stir the solution for about 2 minutes and filter off the un-dissolved solids. washout the solid with about 5mL of C^2H^5OH. 3.Plce about...
