Solubility

Question 1

Suspension

Answer 1

Less soluble, must keep mixing them, largest particles.

Question 2

Solution

Answer 2

Most soluble, stay mixed, smallest particles

Question 3

Answer 4

Shine light through mixture and light scatters

Colloid positive

Question 5

Heterogenous

Answer 5

Can see parts of the mixture

Different composition

Question 6

Homogenous

Answer 6

Same appearance and composition

Question 7

NonElectrolytes

Answer 7

A substance when dissolved that doesnt conduct electricity

Sugar water

Question 8

Electrolyte

Answer 8

A substance when dissolved, conducts electricity

Question 9

How does dissolving occur

Answer 9

The solvent attracts individual particles of solute, pulls them apart and surrounds them.

Question 10

Like dissolves like

Answer 10

Polar dissolved polar

Nonpolar dissolves nonpolar

Question 11

Solute

Answer 11

Is dissolved, lesser amount

Question 12

Solvent

Answer 12

Dissolving medium in a solution, does the dissolving, greater amount

Question 13

Unsaturated solution

Answer 13

Could still dissolve more solute

Question 14

Saturated solution

Answer 14

Contains as much solute as possible

Question 15

Supersaturated solution

Answer 15

As temp increases a given solvent will hold a larger amount of solute

Question 16

Solubility

Answer 16

The ability of a solute to dissolve in a solvent.
As temp increases solubility increases

Answer 21

Electrolytes

Question 22

Dilute

Answer 22

Make a liquid thinner by adding another solvent to it

Question 23

Concentration

Answer 23

Compares the amount of solute in a solution.

Question 24

Concentration and dilute are compared how

Answer 24

Qualitatively

Question 25

Molarity

Answer 25

Number of moles in solute in one liter of solution

Question 26

Molarity formula

Answer 26

Amount of solute(mol)/volume of solution

Question 27

Molality

Answer 27

Measure moles solute and kg solvent separately, then mix

Question 28

G~> kg

Answer 28

3 decimal places to the right

Question 29

Molality formula

Answer 29

Moles solute/kg solvent

Question 30

Hydrate example

Answer 30

CuSO4 * 5H2O Copper 2 sulfate pentahydroxide

Question 31

Hydrate

Answer 31

Attracted forces that connect | When crystallized,some ionic substances form crystals that incorporate water molecules

Question 32

What happens when a crystalline hydrate dissolves in water

Answer 32

The water of hydration returns to the solvent

Question 33

Hydration

Answer 33

solution process with water as the solvent.

Question 34

as hydrated ions diffuse into the solution, other ions are exposed and...

Answer 34

Drawn away from the crystal surface by the solvent

Question 35

Immiscible

Answer 35

Liquids that are t soluble on each other | Oil & water

Question 36

Miscible

Answer 36

Liquids that dissolve freely in one another

Question 37

Pressure and solubility

Answer 37

Increase in pressure, increase gas solubilities in liquids.

Question 38

Effervescence

Answer 38

Escape of a gas from a liquid in which it’s dissolved

Question 39

Henry’s Law

Answer 39

Solubility of a gas in a liquid is directly proportional to the partial pressure of that gas on the surface of the liquid

Question 40

Henry’s law applies to what

Answer 40

Gas liquid solutions at constant temp

Question 41

Enthalpy of solution

Answer 41

Absorption and release of energy when solution is made | Solute solute: molecules in solute held together by intermolecular forces

Question 42

Solvated

Answer 42

A solute particle surrounded by solvent molecules

Question 43

Enthalpy of a solution part 2

Answer 43

Heating decreases the solubility of a gas, so dissolution of gasses is exothermic. Solute solute interaction has little effect on gas enthalpy
