mixture
|
two or more elements/compounds combined physically
|
|
solution
|
mixture when is added to material is so small that it is an atom/ molecule/ ion
|
|
solute
|
material added
|
|
solvent
|
what solute is added to
|
|
5 regulations for solutions
|
stirring to help spread the dissovled particles
dissolved particles will not come out of the solution no matter how long it stands clear adn transparent passes through finest fillters single phase even though components may have been different phases before the solution was formed |
|
ion
|
NaCl
KCl MgF2 NaBr |
|
atom
|
metals
all |
|
molecules
|
sugar C12H22O11
alcohols -ose |
|
polar
|
water is the only polar liquid solid
great at dissolving polar liguid |
|
intermediate
|
alcohols
|
|
non polar
|
gasoline, oils, carbon tetra chloride, glue, gum
|
|
What dissolved what
|
like dissolves like
polar dissolves polar- cleaving of ions - hydration non polar to non polar- lack of intermmolecular attraction does not interfer with mixing |
|
temp
|
increase in temp increase in solubility gases- solubility decreases as temp rises
|
|
Pressure
|
no effect
gas increase solubility increases |
|
rate of solution
|
measure of how fast a substance dissolves
size in particles stiriing increase rate of solution amount of solute already sdissolved temperature |
|
molarity
|
amount of solute (moles) and solvent (liters)
1 molar solution = 1 M soln the molarity of the soln is M the number of moles of solution per liter of total solution |
|
molality
|
particular amount of solvent and particular amount of solute
molality of the solution goe sup the boiling point rises |
