Vocabulary
A combination of two or more substances that are not chemically combined.
What is a mixture?
The part of the mixture that dissolves.
What is a solute?
Particles in these mixtures are spread __________ (evenly or unevenly).
What is unevenly?
This heterogeneous mixture settles without stirring, like a snow globe.
What is a suspension?
This type of separation only works on metals.
What is magnetism?
A type of heterogeneous mixture where particles settle out if not continuously stirred.
What is a suspension
The part of a mixture that does the dissolving.
What is a solvent?
True or False: these mixtures can be a mixture of solids, liquids, and/or gases.
What are True
Can solutions only be liquids, or can they also be solids or gases
No
Separating solutions using heat. (Ex: the Sun drying up a puddle and leaving salt)
What is evaporation?
This force separates materials based on their density.
What is Centrifugal force?
The solute completely dissolves into the solvent.
What is a solution?
This type of mixture has visibly different parts that can be separated by hand, such as trail mix or a bowl of fruit salad.
What is a mechanical mixture
This cloudy mixture suspends particles that don't settle, like milk.
What is a Colloid?
Centrifuge, Separating funnel and Paper Chromatography use this physical property to separate mixtures.
What is density?
The fluid phase of a colloid within which solid or fluid particles are distributed
What is the continuous phase?
2 or more things are combined together and look the same.
What is a homogenous mixture?
These are mixtures of chemical elements, one of which must be a metal.
What is alloys?
This type of mixture includes foams, aerosols, emulsions, and sols, depending on dispersed and continuous phases.
What is a colloid?
Filtration, Filters, and Sieves use this physical property to separate mixtures.
What is particle size?
The phase in a two-phase system that consists of finely divided particles, droplets, or bubbles of one substance distributed through another substance
What is a Dispersed phase?
You CANNOT do this to solutions and homogenous mixtures.
What cannot be physically separated?
This type of mixture has components that are not evenly distributed, allowing the individual parts to be seen, like in a salad or a granite rock.
Heterogenous Mixtures
Shaving cream, where gas disperses in liquid, is this type of colloid.
What is foam?
This separation technique uses differences in boiling points to separate liquids in a mixture. What is the process where a liquid with a lower boiling point vaporizes, rises, and is collected in a cooling tube before condensing back into a liquid
What is distillation?
