Chemestry- Seperating Solutions Flashcards
What is a solution?
A homogeneous mixture of two or more substances.
True or False: A solute is the substance that is dissolved in a solution.
True
What is the process of separating a solid from a liquid in a mixture called?
Filtration
Fill in the blank: The component of a solution that does the dissolving is called the __________.
solvent
What technique can be used to separate a mixture of liquids with different boiling points?
Distillation
True or False: Evaporation can be used to separate a soluble solid from a solution.
True
What is chromatography used for?
To separate and identify components of a mixture based on their movement through a medium.
What is the main difference between filtration and evaporation?
Filtration separates solids from liquids, while evaporation separates liquids from solutions.
What is a common use of crystallization?
To purify solid substances from a solution.
What is the term for a mixture where the components are not uniformly distributed?
Heterogeneous mixture
True or False: In distillation, the liquid with the highest boiling point is collected first.
False
What do you call the liquid that remains after a solid has been filtered out?
Filtrate
Which method would you use to separate sand from salt water?
Filtration followed by evaporation.
Fill in the blank: The process of heating a liquid to create vapor and then cooling it to form a liquid is called __________.
distillation
What property of substances does chromatography rely on?
Different solubilities in a solvent.
What is the purpose of adding a solvent in the process of crystallization?
To dissolve the solute and then allow it to crystallize upon cooling.
Which method is best for separating a mixture of colored dyes?
Chromatography
True or False: All mixtures can be separated by physical means.
True
What is the main principle behind distillation?
Different substances have different boiling points.
What is a saturated solution?
A solution that has dissolved the maximum amount of solute at a given temperature.
Fill in the blank: The solid that forms when a solution is cooled is called __________.
crystals
What is the process of removing a liquid from a solid by applying heat called?
Evaporation
What piece of laboratory equipment is commonly used for filtration?
Filter paper and funnel.
True or False: The process of separating a mixture can involve both physical and chemical changes.
False
What are the two main types of mixtures?
Homogeneous and heterogeneous mixtures.
What is the role of the solvent in a solution?
To dissolve the solute.
