|---|---|---|---|---|---|
| Solutions | Is a homogeneous mixture of two or more substances
🗑
|
||||
| Molarity(M) | Is the strength or concentration of a solute
Molarity= moles of solute/VOLUME of solution
🗑
|
||||
| Molality(m) | Shows the concentration of a solution; the solvent (the compound is the greater amount) units are in kilograms
molality=moles of solute/MASS of solvant
🗑
|
||||
| Soluble | A substance that dissolves in a solvent.
🗑
|
||||
| Slovent | The solvent douse the DISSOLVING (greater amount)
(Ex:Water)
🗑
|
||||
| Miscible | Describes two liquids that are soluble in each other.
🗑
|
||||
| Saturated Solutions | Contains the maximum amount of solute that will dissolve in a given amount of solvent at a specified temp. and pressure.
🗑
|
||||
| Unsaturated Solutions | Contains less dissolved solute for a given temperature and pressure than a saturated solutions.
🗑
|
||||
| Polar molecule |
🗑
|
||||
| 3 collective properties | Vapor Pressure
Boiling Point
Freezing Point
🗑
|
||||
| Vapor Pressure |
🗑
|
||||
| Boiling Point Elevation | The temp. difference between a solution boiling point and pure solvent boiling point.
^Tb=Kbm
🗑
|
||||
| Freezing Point Depression | Freezing-point depression describes the process in which adding a solute to a solvent decreases the freezing point of the solvent
^Tf=Kfm
🗑
|
||||
| Insoluble | A substance that does not dissolves.
🗑
|
||||
| Immiscible | Describes two liquids that can be mixed together but separate shortly after you mix them.
🗑
|
||||
| Supersaturated Solutions | Contains more dissolved solute than a saturated solution at the same temperature
🗑
|
||||
| Solute | The solute is the substance DISSOLVED in the solutions (less amount) (Ex: sugar,salt)
🗑
|
||||
| Aqueous Solutions | Substances dissolved in water
🗑
