states of matter and mixtures: filtration and crystalisation Flashcards
What is the primary purpose of filtration?
To separate solid particles from a liquid or gas.
True or False: Filtration can only be used with liquids.
False
Fill in the blank: The process of _________ involves the formation of solid crystals from a solution.
crystallization
What is the role of a filter paper in the filtration process?
To act as a barrier that allows liquid to pass through while retaining solid particles.
Which of the following is a common method of crystallization? (A) Evaporation (B) Filtration (C) Distillation
A) Evaporation
What is a saturated solution?
A solution that contains the maximum amount of solute that can be dissolved at a given temperature.
True or False: Crystallization can be used to purify substances.
True
What is the term for the solid that forms during crystallization?
Crystal
Describe the process of filtration in one sentence.
Filtration is the process of separating solids from liquids or gases using a porous medium.
In crystallization, what happens when the solution cools down?
The solute becomes less soluble and begins to form crystals.
What is the difference between filtration and centrifugation?
Filtration uses a barrier to separate particles, while centrifugation uses centrifugal force.
Fill in the blank: During crystallization, impurities are often left behind in the ________.
mother liquor
What is one advantage of using crystallization for purification?
It can effectively separate pure crystals from impurities.
True or False: Filtration can be performed using a vacuum.
True
What type of filter is typically used in laboratory filtration?
Filter paper
