|
Water has ____ because of h-bonding
|
unusually high low pressure
|
|
|
solids+energy=
|
solution (saturated)
|
|
|
Stock solution formula
|
M1V1=M2V2
moles before dilution = moles after dilution |
|
|
Suspensions are .. and are not
|
Heterogeneous mixtures where their particles are suspended in medium due to movement - once movement ceases then particles settle out (due to gravity), not true solutions
|
|
|
Particles can be filtered
|
in a suspension but not in solution (or a colliod)
|
|
|
Colloids are
|
somewhere between a solution and a suspension
"glue like" |
|
|
Tyndall Effect
|
the scattering of visible light through colloidal particles
|
|
|
What has the Tyndall Effect?
What does not? |
suspensions, colloids
Solutions |
|
|
Mixtures are composed of 2 phases of matter...
|
1) Dispersed phase (particles)
2) continous phase (medium) |
|
|
Brownian Motion
|
The chaotic movement of collodial particles. This is caused by collisions of the molecules of the dipersion mediam with the small disperesed colloidial particles (keeps them from settling)
|
|
|
4 Types of Colliods
|
1) Liquids and solids dispersed in gases (aersols)
2) Gases dispersed in liquids or solids (foams) 3)liquids dispersed in other liquids or solids (emulsion) 4) Solids dispersed in liquid or solids (Sols) |
|
|
Colligative properties (properties of a solution) include
|
vapor pressure, freezing point, boiling point, and osmotic pressure
|
|
|
Colligative properties are determined by
|
a number of particles in solutions rater than by type
|
|
|
Nonvolatile =
Volatile = |
Low VP, High BP
High VP, low BP |
|
|
Raolts law
|
Vapor pressure of a solution varies directly as the mole fration of the solvent
|
|
|
Raolts law formula
|
Vapor Pressure Solution= Mole Fraction solvent x Vapor pressure of a solvent by an amount that is characteristic of that solvent
