Q

What is a colloid

A

A mixture containing particles larger than most molecules but smaller than 200 nm; Big enough to see, but too small to grab

Q

What is the rate of solution

A

A measure of how fast a substance dissolves

23
Q

What are the four factors that affect the rate of solution

A

The smaller the size of particles, the faster the rate

stirring increases the rate

The more amount of solvent already dissolved, the slower the rate

Temperature

24
Q

What is effervescence

A

The escape of a gas from a solution, alka seltzer

25
Memorize the temperature curve
Aight okay
26
What does Colligative mean
Depending on the collection; a solution that depends only on the quantity of solute particles, not the kind of identity of them
27
Is the role of electrolytes
Conduct electric impulses in your body
28
What are electrolytes
Ionic compounds that dissociate into their respective ions (+ and - parts) and interfere with the solvent particles
29
What are nonelectrolytes
Molecular compounds that do not dissociate. They dissolve as a whole molecule
30
What is an example of an electrolyte
CaCl2 Ca+ , Cl- , Cl- i = 3
31
What is an example of a nonelectrolyte
CH3OH i = 1
32
What is the "i" value called
Van't Hoff Factor
33
What is molarity
The number of moles of solute, divided by the number of liters of solvent
34
What is molality
The number of moles of solute, divided by the number of kilograms of solvent
35
What kind of electrolyte is HCl
A strong electrolytes
35
What kind of electrolyte is distilled water
A nonelectrolyte
36
What kind of electrolyte is tap water
A weak electrolyte
37
What kind of electrolyte is sucrose in water
A nonelectrolyte
38
What kind of electrolyte is acetic acid
A week electrolyte
39
What kind of electrolyte is a NaCl
A strong electrolyte
40
Is water polar or non polar
Polar
41
What happens when you add more solute to an unsaturated solution
It dissolves
42
What happenes when you add more solute to a saturated solution
Extra solute falls to the bottom
43
What happenes when you add more solute to a super saturated solution
ALL extra solute falls to the bottom
44
In solids, as temperature increases what does solubility do
Increase
45
In gases, as temperature increases what does solubility do
Decreases
46
In solids and liquids, as pressure increases what does solubility do
No effect
47
In gases, as pressure increases what does solubility do
Increases
48
Can stirring affect the saturation point
No, it only affects the rate
49
What is dissociation
The dissolving into ions
50
When adding ions into a solution what colligative properties change
Vapor pressure decreases, boiling point raises, freezing point decreases
51
What is an emulsion
Colloid of 2 or more immiscible liquids
52
What are some examples of emulsions
Mayonnaise, margarine, homogenized milk, paint
53
If you spin milk at high velocities, what do you form
Colloid
