Chap 14- Molar Volume
The volume occupied by one mole of a substance- Mv
Chap 15- Boiling Elevations and Freezing Point Depression
The higher the concentration in the solution the higher the boiling point
Chap 15- Colligative Properties
Depend on the concentration of the solution
1. color
2. texture
3. smell/taste

Chap 15- Dilute
less concentrated
Chap 15- Concentrated
Very Concentrated
Chap 15- Colloid
heterogeneous, Tyndall effect, ex. fog
Chap 15- Tyndall effect
when light scatters molecules, like in Fog, or flour in bottle
Chap 15- Molarity
is concentration
Chap 15- saturated
it is at its capacity for matter it can hold
Chap 15- unsaturated
it has space to carry more matter
Chap 15- Factors to inc. solubility
1. stirring
2. heating
3. inc. surface area
4. concentrations
*catalyst
Chap 15- Henry’s Law
Inc. Solubility= Inc. Pressure ex. soda
Chap 15- solutions
solute- smaller amount
solvent- bigger amount(water)
Chap 15- solubility and temperature
gases
inc. temp. = dec. solubility

solids
inc. temp.= inc. solubility

Chap 15- supersaturated
is holding more matter then normal
Chap 15- Molarity
M=n/L

m=n/kg
Chap 19- Indicators
Litmus paper, Phenolphthalein , Ph paper
Chap 19- Phenolphthalein
turns pink ONLY for BASES
Chap 19- Litmus paper
Blue->Red=Acid=BRA
Red->Blue=Base=RBB
Chap 19- Ph
hot colors are acid, cool colors are base, green is neutral.
1-14
1-6= acid
7= neutral
8-14= base
Chap 19- Amphoteric
Being both an acid and a base, like water H2O
Chap 19- Lewis Acids and Bases
Acids are H DONORS
Bases are H ACCEPTERS
Chap 19- Conjugate Acid/Base
related opposite
Chap 19- Neutralization
when an acid and a base are used to make water and a salt and the base and the acid are in equilibrium, when it is turned neutral.
Chap 19- Titration
a way to find concentration of an acid or base by neutralization it in a solution with a unknown concentration.    MAVA  =  MBVB
Chap 19- Acid Properties
sour, corrosive,is an electrolyte, covalent, ionizes, dehydrating agent, exists as an aqueous solution
Chap 19- Base Proprties
bitter, corrosive, slimy, is an electrolyte, ionic, dissolves, breaks up oil and fat, dehydrating agent
Chap 19- To find the Ph or POH
-log it to find the Ph, and -log to find the POH and subtract from 14. The number you log must be the Molarity (M)
