  • Front

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
