A process of purifying a liquid by heating and cooling.

Question 2

What is the definition of Solube?

Answer 2

A substance able to be dissolved, especially in a liquid (If the liquid is clear)

Question 3

What is the definition of Insoluble?

Answer 3

A substance incapable of being dissolved. (If the liquid is cloudy)

Question 4

What is the definition of Suspension?

Answer 4

Mixture in which the solid particles are spread throughout the liquid without dissolving. (Insolube)

Question 5

What is the definition of Homogenisation?

Answer 5

A process of blending things together to form a mixture that is the same throughout.

Question 6

What is the definition of Chromatography?

Answer 6

A process/technique used to separate components of a mixture. (eg. separating colours from ink or paint)

Question 7

What is the definition of Solute?

Answer 7

Is a minor component in a solution that dissolves in the solvent.

Question 8

What is the definition of Dilute?

Answer 8

To make a liquid thinner or weaker by adding water or another solvent to it. (More solvent = more dilute)

Question 9

What is the definition of Sediment?

Answer 9

Matter that sinks to the bottom of a liquid. (Insoluble)

Question 10

What is the definition of Goluble?

Answer 10

A small droplet of a liquid. (eg. liquid chemicals or substances)

Question 11

What is the definition of Solvent?

Answer 11

A chemical or liquid that can dissolve other substances.

Question 12

What is the definition of Solution?

Answer 12

A liquid mixture in which the solute is evenly distributed within the solvent.

Question 13

What is the definition of Evaporation?

Answer 13

The process of turning from a liquid into a gas.

Question 14

What is the definition of Concentrated?

Answer 14

The quantity of solute present in a quantity of solution. (more solute = more concentrated solution)

Question 15

What is the definition of Residue?

Answer 15

A substance that remains after a process such as combustion or evaporation.

Question 16

What is the definition of Filtration?

Answer 16

The process of filtering something.

Question 17

What is the definition of Condensation?

Answer 17

The conversion of a gas to a liquid.

Question 18

What is the definition of Colloid?

Answer 18

Any substance consisting of particles substantially larger than atoms or ordinary molecules but too small to be visible to the unaided eye. (colloids are cloudy)

Question 19

What is the definition of Mixture?

Answer 19

A substance is made by mixing other substances together. (seawater, air and ink)

Question 20

What is the definition of Filtrate?

Answer 20

A liquid that has passed through a filter.

Question 21

What is the definition of Pure Substance?

Answer 21

A single kind of matter that cannot be separated (eg. gold)

Question 22

What is the definition of Emulison?

Answer 22

The dispersion of droplets of one liquid in another that is insoluble or can’t dissolve.

Question 23

What is the definition of Decanting?

Answer 23

To slowly pour a liquid from one container to another. (usually to separate the sediment from the liquid)

Question 24

What is the definition of Crystallisation?

Answer 24

A process of concentrating a solution to the formation of solid particles in a homogeneous phase.

Question 25

What is the definition of a Separating Funnel?

Answer 25

A process of separating components of a mixture into a solid depending on the density of the solid.
