Chemistry Unit 4 Flashcards
colloid
where the particles of one substance don’t dissolve but stay distributed through another substance
concentrated
a solution with a large amount of solute
decantation
the process of separating by using gravity
dilute
a solution with only a small amount of solute
emulsion
two or more liquids trying to separate
evaporation
when heat causes liquid to become gas
filtrate
the substance that passes through the filter
filtration
separating a mixture by passing through a filter
flocculent
a substance that causes particles to clump
flotation
separating a mixture based on its capacity to float
heterogeneous mixture
a mixture that can be easily separated into its parts
homogeneous mixture
a mixture where components are evenly distributed
insoluble
substances that cannot dissolve
mixture
a substance made up of two or more different substances
pure substance
a substance that is just made up of one particle
residue
the substance that is left in the filter
saturated
a solution with the maximum amount of solute dissolved
soluble
substances that can dissolve
solution
a mixture where one substance is evenly dissolved in another
solvent
a solution capable of dissolving another substance
suspension
a mixture where one substance will eventually settle out of the solvent
aqueous solution
solutions where the solvent is water
centrifugue
a device that uses speed to separate substances based on mass (blood spinning in the thing)
chromotography
a technique used to separate substances based on movement at different rates due to solubility (texter on paper)
crytallisation
solidification of a substance into highly structured form
distillation
a technique used to separate substances in a liquid using evaporation through boiling and condensation
smog
a mixture of smoke, gasses and chemicals, especially in cities
