1
Q

Homogenous

A

Completely blended

2
Q

Solute

A

Substance that dissolves

3
Q

Solvent

A

What is doing the dissolving

4
Q

Suspension

A

Mixture containing particles that settle out if undisturbed

Muddy water

5
Q

Thixotropic

A

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

6
Q

Colloid

A

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

Milk

7
Q

Brownian motion

A

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.

8
Q

Tyndall effect

A

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

9
Q

Miscible

A

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

Antifreeze

10
Q

Two liquids that can be mixed together but separate shortly after

Ex: water and suntan oil

A

Immiscible

11
Q

Dilution equation only works for…

A

1:1 ratios

12
Q

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

A

Silver ion

13
Q

“Like dissolves like”

How do you determine this?

A

Bonding and polarity of particles and intermolecular forces

14
Q

Heterogeneous

A

Not blended

15
Q

Put the___in the____

A

Solute (loot)

Solvent (vent)

16
Q

Electrolytes are___

A

Ionic

17
Q

Non Electrolytes are_____

A

Covalent

18
Q

Alloys are an example of a____

A

Homogenous mixture

19
Q

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

A

Solvation

20
Q

Polar does not dissolve

A

Nonpolar

21
Q

Does solvation require energy?

A

Yes because the solute must separate into particles and move apart

22
Q

Overall energy change that occurs during solution formation

A

Heat of solution

23
Q

Factors that affect Solvation

Increases collisions between particles

A

Agitation
Surface area
Temperature

24
Q

Solvation of gases_____at a higher temperature

A

Decreases

25
Q

Unsaturated

A

More solute can be dissolved

26
Q

Saturated

A

Maximum amount

27
Q

Supersaturated solutions are_____and contain____dissolved solute than a saturated

A

Unstable, more

28
Q

How are supersaturated solutions created?

A

Saturated at high temperature then cooled

29
Q

Henry’s law

A

S1/P1 = S2/P2

30
Q

Collimating property

A

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

31
Q

Pressure that has particles exert back on liquid in closed container

Inversely proportional to IMF

A

vapor pressure

32
Q

Nonvolatile

A

Doesn’t want to be a gas

33
Q

Adding nonvolatile solute____the VP

A

Lowers

34
Q

The variable I equals the____

A

Number of compounds

35
Q

The freezing point of a solution is always____than that of a pure solvent

A

Lower

36
Q

Osmosis

A

Diffusion of solvent through a semipermeable membrane
