Liquids Test (4/29/16)

Question 1

The most abundant substance in a solution

Answer 1

Solvent

Question 2

Dissolved substances

Answer 2

Solute

Question 3

When 2 liquids mix to form homogeneous mixture

Answer 3

Miscible

Question 4

When liquids separate after mixing

Answer 4

Immiscible

Question 5

The dissolving process in solid-in-liquid solutions

Answer 5

Solvation

Question 6

Solvation in water

Answer 6

Hydration

Question 7

The net energy change during the dissolving process

Answer 7

Enthalpy

Question 8

The energy goes from the motion of the particles and enters the bonds

Answer 8

Endothermic

Question 9

The energy exits the bonds and increases the motion, thus the solution heats up

Answer 9

Exothermic

Question 10

When more solute can still be dissolved

Answer 10

Unsaturated

Question 11

When a solution contains the maximum amount of a solute

Answer 11

Saturated

Question 12

When a solution contains more dissolved solute than it does at equilibrium

Answer 12

Supersaturation

Question 13

When both the solute and solvent occur at the same rate and are balanced

Answer 13

Dynamic equilibrium

Question 14

When ions are so tightly bound together that you cannot pull them apart

Answer 14

Insoluble

Question 15

Is a measure of the number of solute particles in a certain volume or mass of the solvent, or of the solution itself. Concentration= amount of solute/ amount of solution (or solvent)

Answer 15

Concentration

Question 16

Comparison of the solute to the mass of the solution. % by mass= mass of solute/ massof solution x 100%

Answer 16

Percent by mass

Question 17

Comparison of volume of the solute to the volume of the solution. % by volume= volume of solute/ volume of solution x 100%

Answer 17

Percent by volume

Question 18

The number of moles of solute per liter of solution. Most common expression of Concentration

Answer 18

Molarity

Question 19

number of moles of solutes per kilogram of solvent.

Answer 19

Molality

Question 20

The new properties of a solution that depend upon the number of particles in the solution.

Answer 20

Colligative properties

Question 21

The change in boiling point

Answer 21

Boiling-point Elevation

Question 22

1 mole of particles- molecules, atoms, or ions- in 1 kilogram of water elevates the boiling point of water 0.512 C

Answer 22

Molal Boiling-point constant

Question 23

The change in freezing point

Answer 23

Freezing-point depression

Question 24

Each solvent has its own that is found by multiplying the molality to find the magnitude

Answer 24

Molal freezing-point constant

Question 25

The process in which a solvent moves across a semipermeable membrane

Answer 25

Osmosis

Question 26

The amount of pressure required to prevent osmosis from occurring.

Answer 26

Osmotic Pressure

Question 27

Mixtures that contain small particles dispersed in a medium.

Answer 27

Colloids

Question 28

Particles in a colloid (ie. water vapor in a fog)

Answer 28

Dispersed Phase

Question 29

The medium of a colloid (ie., air for fog)

Answer 29

Dispersing Medium

Question 30

LCD

Answer 30

Liquid Crystal Displays

Question 31

A graphical way to summarize the temperature and pressure conditions in which a substance exists as a solid, liquid , or gas.

Answer 31

Phase Diagram

Question 32

The process of vaporization and condensation can be used to separate mixtures

Answer 32

Distillation

Question 33

A rapid change between liquid and the gaseous states caused by the application of heat

Answer 33

Boiling

Question 34

A cooling process that occurs in a non-boiling liquid

Answer 34

Evaporization

Question 35

The reverse of vaporization- it is the formation of a liquid from its gaseous state.

Answer 35

Condensation

Question 36

Can occur at or below the boiling- point, and is where molecules break away from the liquid because of their speed

Answer 36

Vaporization

Question 37

The concave surface that occurs as a result of adhesion for a liquid

Answer 37

Meniscus

Question 38

A liquids ability to flow

Answer 38

Viscosity

Question 39

A liquids resistance to flow

Answer 39

Adhesion

Question 40

The "skin" that forms on the surface of a liquid

Answer 40

Surface tension

Question 41

The attraction between particles in liquid

Answer 41

Cohesion

Question 42
