Seperation Techniques Flashcards
Study (13 cards)
What is the key concept associated with the study of matter and its composition?
Change
Related concepts include form, condition, and interaction.
What is the global context for the study of matter and its composition?
Personal and cultural expression
It involves reflecting on, extending, and enjoying creativity, and appreciating aesthetics.
What is distillation used for?
To separate liquids from nonvolatile solids and to separate two or more liquids having different boiling points
Examples include separation of alcoholic liquors and petroleum products.
What equipment is required for the basic operation of distillation?
A still or retort, a condenser, and a receiver
The still heats the liquid, the condenser cools the vapor, and the receiver collects the distillate.
What is the principle behind fractional distillation?
It is used to separate liquids whose boiling points lie close to one another
This method is essential in applications like petroleum refining.
Give an example of a mixture that can be separated by distillation.
Ethanol and water
Other examples include acetone and water.
What is a separating funnel used for?
To separate components of a mixture of immiscible liquids
The funnel allows for the separation based on density.
What happens when kerosene oil and water are mixed in a separating funnel?
They form two separate layers based on their densities
Water is the lower layer, and kerosene is the upper layer.
Which of the following can be separated using a separating funnel?
Water and kerosene mixture
Acetone and water mixture cannot be separated this way.
Fill in the blank: The process of distillation is used for liquids having _______.
Sufficient difference in their boiling point.
What are the basic methods of distillation?
Fractional distillation and simple distillation
Other methods may include steam distillation and destructive distillation.
True or False: Simple distillation can separate milk from water.
False
Distillation is not effective for separating milk from water.
Differentiate between separation by distillation and separatory funnel.
Separation by distillation is for miscible liquids based on boiling points; separatory funnel is for immiscible liquids based on densities.
