  1. 1. Technological Institute of the Philippines 938 Aurora Blvd., Quezon City Experiment no. 3 Basic Separation Technique Submitted By: Group No.2 of Section ES11FB4 MEMBERS TASK PERFORMANCE TIME IN TIME OUT LAB GOWN (X/√) SIGNATURES OF MEMBERS Davis Banoog 1:30 4:30 Jenny-Ann Cabrera 1:30 4:30 Luis Miguel Benitez 1:30 4:30 Date Performed: July 12, 2013 Date Submitted: July 27, 2013 Engr.

  2. 2. OBJECTIVES: 1.1To separate components of mixture using basic separation techniques APPARATUS AND MATERIALS: THEORY: Substances in nature appear either in the pure form or as components of a mixture. When mixtures are formed, the pure components may be recovered by employing physical separation processes. Some of the common separation processes are filtration, evaporation, extraction, sublimation, distillation and magnetic attraction. 1 Magnet 1 Filter Paper 1 Cotton Plug 4 100 ml Beaker 1 50 ml Graduated Cylinder 1 Funnel 1 Stirring Rod 1 Bunsen Burner 2 Watch Glass 1 Test Tube 1 125 ml Erlenmeyer Flask 1 Iron Stand 1 Iron Ring 1 Wire Gauze 1 Mortar and Pestle NaCl Powder Naphthalene Powder Iron Fillings Food Color Water Activated Carbon / Charcoal
  3. 3. PROCEDURE: 1. As the experiment is conducted, accomplish the schematic diagram provided on the next page to show the separation of mixture. 2. Prepare the following substances: table salt, food color powder, naphthalene or moth balls and iron filings. Note the properties of each substance and accomplish Table 3.1. 3. Prepare a mixture consisting of the above substances and spread the mixture thinly on a piece of white paper. Pass a magnet under the paper moving it from the center towards the side of the paper until separation of some components is observed. 4. Transfer the remaining mixture into a beaker, add 25 ml of water and stir well. Filter off the undissolved solids and save both the residue and the filtrate Note the color of the filtrate. 5. Transfer the filtrate from step 4 to the beaker and add 1 gram of activated charcoal. Heat the solution to boiling with stirring and continue boiling for 2 minutes. Filter and save the filtrate for the next step. 6. Carefully transfer the residue from step 4 into an evaporating dish. Cover the dish with perforated filter paper and on top of the dish with a low flame until some solids deposit on the walls of the funnel. Save both the deposit and the residue. 7. Heat and evaporate the filtrate from procedure 5 to dryness. Cool and identify the residue.

  7. 7. QUESTION AND ANSWERS: 1. Refer to procedure no. 3. 1.1 Which component was separated? Components of iron filings were separated from other components. 1.2 What do you call this type of separation? This type of separation is called magnetic attraction or separation. 1.3 When do you use this method of separation? We use this type of separation when we separate metal from other non-metal components. 2. Refer to procedure no. 4. 2.1 What method of separation was utilized? This method of separation is called filtration. 2.2 When do you use this method of separation? We use this type of separation to separate the liquid from the solids, mostly suspensions. The residue is then collected on the filter paper. 2.3 Which components dissolved in water? Components that dissolved in the water are the food color and the NaCl. 2.4 Which components are in the residue? Naphthalene components were separated. 3. Refer to procedure no. 5. 3.1 What method of separation was employed? 3.2 When do you use this type of separation? 3.3 Identify the solid deposit and the residue. 4. Refer to procedure no. 6. 4.1 Identify the method of separation employed.
  8. 8. 4.2 Compare the color of the filtrate with that obtained in step 3. 4.3 Which components were left in the residue? 5. Refer to procedure no. 7. 5.1 Describe the residue. 5.2 When do you use this type of separation?
