27 Cards in this Set

  • Front
  • Back
homogeneous mixture
the same throughout
solvent
does the dissolving
solute
is dissolved
soluble
dissolve very easily
insoluble
don't dissolve easily
miscible
liquids that are dissolved in each other
immiscible
liquids that can't disolve in each other
solvation
the dissolving process
3 factors that increase solvation
-increase surface area
-increase temperature
-stirring
exothermic
gives off heat(gets colder)
endothermic
takes in heat(gets hotter)
solubility
maximum amount of solute in a given amount of solvent at a specified temperature
unsaturated
can still dissolve solute
saturated
maximum amount of solute is dissolved(syn. for solubility)
supersaturated
more solute than it should be able to hold
factors affecting solubility
temperature and gases
Henry's Law
s1/p1=s2/p2
solution concentration
comparing the amount of solute to the amount of solvent
ppm
parts per million
percent by mass
mass of solute/mass of solution x100
percent by volume
volume of solute/volume of solutionx100
molarity
1 mol solute/ 1 mol solution
molality
1 mol solute/ 1 Kg solution
diluting solutions
m1v1=m2v2
mole fraction
moles of solute/ moles of solute+moles of solvent
boiling point elevation
delta Tb= Kbm
freezing point depression
delta Tf= Kfm
