Mixtures And Solutions

Question 1

Homogenous

Answer 1

Completely blended

Question 2

Solute

Answer 2

Substance that dissolves

Question 3

Solvent

Answer 3

What is doing the dissolving

Question 4

Suspension

Answer 4

Mixture containing particles that settle out if undisturbed

Muddy water

Question 5

Thixotropic

Answer 5

Suspension that separates into a solid mixture on bottom and water on the top (solid like mixture that can flow like liquid)

Toothpaste or paint

Question 6

Colloid

Answer 6

Mixture that has intermediate sized particles, doesn’t settle out, can’t be filtered

Milk

Question 7

Brownian motion

Answer 7

States that dispersed particles of liquid colloids make jerky, random movements. Results from the collisions of particles of the dispersion medium with the dispersed particles. Collisions help prevent colloid particles from settling out.

Question 8

Tyndall effect

Answer 8

Scattering of light by dispersed colloid particles, suspension exhibit this but solutions do not, can be used to determine the amount of colloid particles suspended in the air

Ex: light passing through smoke

Question 9

Miscible

Answer 9

Two liquids that are so liable in each other in any proportion

Antifreeze

Question 10

Two liquids that can be mixed together but separate shortly after

Ex: water and suntan oil

Answer 10

Immiscible

Question 11

Dilution equation only works for…

Answer 11

1:1 ratios

Question 12

Process of surrounding solute particles with solvent particles to form a solution

Answer 12

Silver ion

Question 13

“Like dissolves like”

How do you determine this?

Answer 13

Bonding and polarity of particles and intermolecular forces

Question 14

Heterogeneous

Answer 14

Not blended

Question 15

Put the___in the____

Answer 15

Solute (loot)

Solvent (vent)

Question 16

Electrolytes are___

Answer 16

Ionic

Question 17

Non Electrolytes are_____

Answer 17

Covalent

Question 18

Alloys are an example of a____

Answer 18

Homogenous mixture

Question 19

Process of surrounding solute particles with solvent particles to form a solution

Answer 19

Solvation

Question 20

Polar does not dissolve

Answer 20

Nonpolar

Question 21

Does solvation require energy?

Answer 21

Yes because the solute must separate into particles and move apart

Question 22

Overall energy change that occurs during solution formation

Answer 22

Heat of solution

Factors that affect Solvation

Increases collisions between particles

Answer 23

Agitation
Surface area
Temperature

Solvation of gases_____at a higher temperature

Answer 24

Decreases

Unsaturated

Answer 25

More solute can be dissolved

Question 26

Saturated

Answer 26

Maximum amount

Question 27

Supersaturated solutions are_____and contain____dissolved solute than a saturated

Answer 27

Unstable, more

Question 28

How are supersaturated solutions created?

Answer 28

Saturated at high temperature then cooled

Question 29

Henry’s law

Answer 29

S1/P1 = S2/P2

Question 30

Collimating property

Answer 30

Physical properties of solution are affected by the number of particles not the identity

Inversely proportional to IMF

Answer 31

vapor pressure
