Chemistry 12 Test

Front 1

Soluble

Back 1

Capable of being dissolved.

Front 2

Solution

Back 2

A homogeneous mixture of two or more substances in a single phase.

Front 3

Solvent

Back 3

The dissolving medium in a solution.

Front 4

Solute

Back 4

The substance dissolved in a solution.

Front 5

Suspension

Back 5

When the particles in a solvent are so large that they settle out unless the mixture is constantly stirred or agitated.

Front 6

Colloid

Back 6

When the particles are intermidiate sized between a solution and a suspension.

Front 7

Electrolyte

Back 7

A substance that dissolves in water to give a solution that conducts electric currents.

Front 8

Non Electrolyte

Back 8

a subsatnce that dissoles in water to give a solution that does not conduct electric currents

Front 9

Solution Equilibrium

Back 9

the physical state in which the opposing process of dissolution and crystallization of a solute occur at equal rates.

Front 10

Saturated Solution

Back 10

A solution that contains the maximum amount of dissolved solute.

Front 11

Unsturated solution

Back 11

A solution that contains less solute than a saturated solution under the existing conditions.

Front 12

Supersaturated solution

Back 12

a solution that contains more dissolved solute than a saturated solution contains under the same conditions.

Front 13

solubility

Back 13

is the amount of that substance required to form a saturated solution with a specific amount of solvent at a specified temperature.

Front 14

hydration

Back 14

The solution process with water as the solvent.

Front 15

immiscible

Back 15

Liquids that are not soluable in each other.

Front 16

miscible

Back 16

Liquids that dissolve freely in one another in any proportion.

Front 17

Henry's law

Back 17

The solubility of a gas in a liquid is directly proportional to the partial pressure of that gas on the surface of the liquid.

Front 18

effervscence

Back 18

The rapid escape of a gas from a liquid in which it is dissolved.

Front 19

solvated

Back 19

A solute particle that is surrounded by solvent molecuels.

Front 20

enthalpy of a solution

Back 20

The net amount of energy absorbed as heat by the solution when a specific amount of solute dissolved in a solution

Front 21

Concentration

Back 21

a measure of teh amount of solute in a given amount of solvent or solution.

Front 22

Molarity

Back 22

the number of moles in one liter of solution.

Front 23

Molality

Back 23

The concentration of a solution expressed in moles of solute per kilogram solvent.
