1

continuous phase

When there is an unbroken phase

2

dispersed phase

A phase that is a minority in a heterogeneous mixture and that is dispersed throughout the continuous phase

3

gel

Consist of a solid dispersed in a liquid

4

sol

If the solid in liquid mixture is more like a liquid than a gel

5

emulsion

A heterogeneous mixture that contains two or more immiscible particles

6

immiscible

Not able to dissolve into another

7

foam

Forms when a gas is whipped into a liquid so that it makes a mixture of bubbles within the liquid

8

aerosol

Tiny solid particles or liquid drops that are dispersed in a gas

9

colloidal dispersion

If the particles are between 1nm and 1um

10

suspension

Fluid mixtures whose dispersed particles are larger than 1um in size

11

Tyndall effect

When a beam of light shines through a mixture and can be clearly seen

12

solution

Uniform mixtures of pure substances that consist of a single phase

13

solute

The substance that is to be dissolved

14

solvent

The substance that does the dissolving

15

amalgam

The substance formed when mercury is dissolved in gold

16

dissociation

Ions are pulled and wedged from the crystal

17

soluble

A substance is soluble when it can be dissolved by a solvent.

18

miscible

Liquids that can freely mix in any proportion.

19

solubility

The maximum amount of solute that will be dissolved in a given amount of solvent at a given temperature

20

insoluble

Solutes that cannot mix in certain solvents

21

Henry's Law

States that the greater the pressure of a gas on a liquid the greater the mass of the gas that will remain dissolved at any given temperature.

22

saturated

No more solute can be dissolved in the solvent at this temperature.

23

unsaturated

Solutions that contain less solute than their solubility

24

supersaturated

Has more dissolved solute than a saturated solution should have at a given temperature

25

concentration

How much solute in the solution

26

percentage by mass

The percent of solute in the solution

27

mole (mol)

An SI base unit

28

molarity (M)

Solution concentration measured in intifada of moles of solute per liter of solution.

29

colligative properties

A physical property of a solvent that depends on the concentration of the solute particles and not the kind of solute.

30

freezing-point depression

The number of degrees the freezing point of a solvent is reduced per mole of dissolved solute particles a colligative property of the solvent.
