Disterlation Flashcards
(15 cards)
What is distillation?
Distillation is a separation process that relies on differences in boiling points to separate components in a mixture.
True or False: Distillation can only be used for liquid mixtures.
False
What is the primary purpose of distillation?
The primary purpose of distillation is to purify a liquid or separate components based on their boiling points.
Fill in the blank: The process of heating a liquid to create vapor and then cooling that vapor to create a liquid is called __________.
distillation
In which type of distillation is the mixture heated in a still and the vapor passes through a condenser?
Simple distillation
What is fractional distillation?
Fractional distillation is a method used to separate a mixture into its individual components based on different boiling points using a fractionating column.
Multiple Choice: Which of the following is NOT a type of distillation? A) Simple B) Fractional C) Reverse D) Steam
C) Reverse
What is a key factor that affects the efficiency of distillation?
The difference in boiling points of the components being separated.
True or False: Distillation can be used to separate azeotropic mixtures.
False
What apparatus is commonly used in distillation?
A distillation flask, condenser, and receiving flask.
Fill in the blank: The liquid that is collected after condensation in distillation is called the __________.
distillate
What is the main advantage of using vacuum distillation?
It allows distillation at lower temperatures, which is useful for heat-sensitive materials.
Multiple Choice: Which type of distillation is best for separating components with very close boiling points? A) Simple B) Fractional C) Steam D) Vacuum
B) Fractional
What is the term for the temperature at which a liquid turns into vapor?
Boiling point
True or False: Distillation can only be performed on homogeneous mixtures.
False
