Activity 6.5:
Aim: To separate a mixture using distillation method.
Apparatus and Materials: Mixture of water and alcohol, porcelain chips, thermometer, tripod stand, Bunsen burner, wire gauze, Liebig condenser, retort stand with clamp, round-bottom flask, beaker.
Instruction
1. Pour the mixture of water and alcohol into the round-bottom flask until it is half full and add in some porcelain chips.
2. Flow the water through the Liebig condenser (Figure 6.21).
3. Heat the mixture of water and alcohol and collect the liquid that flows out of the Liebig condenser using a beaker.
4. Record the temperature of the liquid. Determine the boiling point of the liquid.
Questions
1. At what temperature does the liquid start to flow out of the condenser?
2. What is the use of porcelain chips in this experiment?
Answer:
1. 78°C
2. To prevent the solution in the flask from jumping.
