Question:
Explain Fractional Distillation. Use Crude Oil as an example.
Author: eric_galvaoAnswer:
1. Pour your mixture into a Flask. Attach said flask then to a Fractionating column that is filled with Glass Rods. 2. Heat up the mixture slowly. The different liquids again have different boiling points meaning they will evaporate at different temperatures 3. The liquid with the Lowest Boiling point will evaporate first. When the thermometer has reached the boiling point for that liquid, it will allow it to reach the Top of the Fractionating column. Other liquids may also evaporate [as there similar] but fail to reach the top, as its colder there meaning they will condense and go back down. 4. The Chosen liquid will then flow through the Condenser and fill up a Flask or a Measuring Cylinder. You then repeat to get the next one.
