Chapter 14 Vocab

Question 1

Colloid

Answer 1

A heterogeneous mix of intermediate sized particles

Question 2

Concentration

Answer 2

A measure of how much solute is dissolved in a specific amount of solvent or solution

Question 3

Crystallization

Answer 3

A separation technique that produces pure solid particles of a substance from a solution that contains the dissolved substance

Question 4

Brownian motion

Answer 4

Erratic, random, moments of colloid particles that results from collisions of particles of the dispersion medium with the dispersed particles

Question 5

Distillation

Answer 5

A technique that can be used to physically separate most homogeneous mixtures based on the differences in the boiling points of the substances

Question 6

Filtration

Answer 6

A technique that uses a porous barrier to separate a solid from a liquid

Question 7

Heterogeneous mixture

Answer 7

One that does not have a uniform composition and in which the individual substances remain distinct

Question 8

Homogeneous mixture

Answer 8

One that has a uniform composition throughout and always has a single phase

Question 9

Insoluble

Answer 9

Describes a substance that cannot be dissolved in a given solvent

Question 10

Mixture

Answer 10

A physical blend of two or more pure substances in any proportion in which each substance retains its individual properties

Question 11

Molarity

Answer 11

The number of miles of solute dissolved per liter of solution

Question 12

Saturated solution

Answer 12

Contains the maximum amount of dissolved solute for a given amount of solvent at a specific temperature and pressure

Question 13

Soluble

Answer 13

Describes a substance that can be dissolved in a given solvent

Question 14

Solution

Answer 14

A uniform mixture that can contain solids liquids or gases

Question 15

Solvation

Answer 15

The process of surrounding solute particles with solvent particles to form a solution

Question 16

Suspension

Answer 16

A type of heterogeneous mixture whose particles settle out over time and can be separated from the mixture by filtration

Question 17

Supersaturated solution

Answer 17

Contains more dissolved solute than a saturated solution at the same temperature

Question 18

Tyndall effect

Answer 18

The scattering of light by colloidal particles

Question 19

Unsaturated solution

Answer 19

Contains less dissolved solute for a given temperature and pressure than a saturated solution

Question 20

Chromatography

Answer 20

A technique that separates the components of a mixture based on the tendency of each component to travel or be drawn across the surface of another material
