Separation Techniques 1Q

Question 1

It is the process of separating the
insoluble solid from the liquid
substance by allowing the liquid to
pass through a porous material called filtering agent

Answer 1

Filtration

Question 2

This is a method used to separate
the liquid layer known as
supernatant and a heavy insoluble
solid known as precipitate by
allowing the said solid to settle at
the bottom of the container then the liquid above the solid is poured off carefully into another container

Answer 2

Decantation

Question 3

This involves the use of forceps,
sieves, magnet and other similar
tools to separate the components of mixtures. Sand and gravel are
separated by passing the mixture
over a wire screen

Answer 3

Mechanical
Separation

Question 4

This is a process that involves the
evaporation and condensation of a
liquid solvent from a mixture or
solution. This method uses the
difference in boiling points of the
components of a mixture.

Answer 4

Distillation

Question 5

This process uses the difference in
the degrees to which substances are absorbed on the surface of an inert substance such as a filter paper

Answer 5

Chromatography

Question 6

This is a chemical decomposition or breakdown produced by passing an electric current through a liquid or solution containing ions.

Answer 6

Electrolysis

Question 7

It is the process that uses a motor
device known as centrifuge that
speeds up the settling of the
precipitate using centrifugal or
rotating motion

Answer 7

Centrifugation
