55 cards
Card 1
Question: What is distillation primarily used for?
Answer: To separate components of a liquid mixture.
Card 2
Question: What physical property do different substances rely on for separation in distillation?
Answer: Different boiling points.
Card 3
Question: What happens to the component with the lower boiling point when a liquid mixture is heated during distillation?
Answer: It will vaporize more readily.
Card 4
Question: How is the more volatile component separated after it vaporizes in distillation?
Answer: It is cooled and condensed back into a liquid.
Card 5
Question: What is the core principle behind distillation?
Answer: The difference in vapor pressures and, consequently, boiling points of the components in a mixture.
Card 6
Question: What is the boiling point of a liquid?
Answer: The temperature at which its vapor pressure equals the surrounding atmospheric pressure.
Card 7
Question: Which component in a two-liquid mixture will have a higher vapor pressure at any given temperature below its boiling point?
Answer: The component with a lower boiling point.
Card 8
Question: What is the condensed liquid collected in distillation called?
Answer: The distillate or condensate.
Card 9
Question: What happens to the remaining liquid in the original vessel after distillation?
Answer: It becomes enriched in the less volatile components.
Card 10
Question: What is the purpose of the distillation flask in a distillation setup?
Answer: It is the vessel where the liquid mixture to be separated is heated.
