Question

Match each term to the correct definition.

A. Chemical separation

B. Gravity filtration

C. Physical separation

D. Vacuum filtration

E. Evaporation

F. Heterogeneous mixture

G. Homogenous mixture

H. Distillation

I. Extraction

J. Decantation

-varies in composition, distinct clumps of each component appear in the mixture

-uniform in composition, the components cannot be visually distinguished

-uses heat to remove a volatile solvent from a dissolved solution, leaving behind the non-volatile components as a solid residue

-exploit some difference in the physical properties of two species in order to separate them

-exploit reactivity to convert one component to a new species which can be easily separated from the other components that are present

-uses a solvent to selectively dissolve one component while leaving other components in the solid state

-uses gravity to pull the liquid through a filter paper to separate a liquid from a solid

-uses a vacuum to pull the liquid through a filter paper to separate a liquid from a solid.

-The process of pouring a solution off a heavy solid that settles to the bottom of the container

-Takes advantage of the difference in the boiling point between the two components

Answer 1

A. Chemical separation = uses a solvent to selectively dissolve one component while leaving other components in the solid state

B. Gravity filtration = uses gravity to pull the liquid through a filter paper to separate a liquid from a solid

C. Physical separation = exploit some difference in the physical properties of two species in order to separate them

D. Vacuum filtration = uses a vacuum to pull the liquid through a filter paper to separate a liquid from a solid.

E. Evaporation = uses heat to remove a volatile solvent from a dissolved solution, leaving behind the non-volatile components as a solid residue

F. Heterogeneous mixture = varies in composition, distinct clumps of each component appear in the mixture

G. Homogenous mixture = uniform in composition, the components cannot be visually distinguished

H. Distillation = Takes advantage of the difference in the boiling point between the two components

I. Extraction = exploit reactivity to convert one component to a new species which can be easily separated from the other components that are present

J. Decantation =The process of pouring a solution off a heavy solid that settles to the bottom of the container
