Fractional Distillation
6 cards
Card 1
Question: What is fractional distillation?
Answer: Fractional distillation is a physical separation process used to separate components of a liquid mixture based on differences in their boiling points,
Card 2
Question: What is another name for fractional distillation?
Answer: Rectification.
Card 3
Question: What is the key principle behind fractional distillation?
Answer: Repeated vaporization and condensation cycles within a single apparatus, the fractional distillation column.
Card 4
Question: How does fractional distillation differ from simple distillation in terms of vaporization and condensation steps?
Answer: Fractional distillation involves many vaporization-condensation steps in succession, while simple distillation involves a single vaporization-condensa
Card 5
Question: How does each successive vaporization and condensation step affect the vapor and remaining liquid in fractional distillation?
Answer: Each step enriches the vapor in the more volatile component and the remaining liquid in the less volatile component.
Card 6
Question: If a binary mixture of liquids A and B is heated, and A is more volatile than B, what happens to the vapor produced?
Answer: The vapor produced will be richer in A than the original liquid.
