 Dissociation
 Solutions
 Suspensions
 Colloids
 Allows
continual contact between
solute & solvent
 Heterogeneous
 Solutions
 Aerosols
 Foams
 Emulsions
 Gels/Sols
 Ions
are not dissociated and the
ions are not mobile since the are
not in a solution
 Solvent
 Electrolyte
 Heating
 Stirring
 Grinding
 Increases
the kinetic energy so
molecules are moving faster so
more collisions between the
solute & solvent
 Colloid
 Saturated
 State
where the solute is
dissolving at the same rate that
the solute is coming out of
solution (crystallizing).
 Solubility
 Creates
more of a surface area on
the solute, so more collisions
between solute & solvent will
occur
 Solvation
 Saturated
Solution
 Brownian
Motion
 Ions
are dissociated and the ions
are mobile
 Suspension
 Tyndall
Effect
 Undissolved
solute would be
present at the bottom of the
container

rule of thumb for predicting
whether or not one substance
dissolves in another


Ex: Polar solutes will dissolve in polar
solvents
 Aerosols
 Solute-solute
attraction is broken
up; requires energy
 Solvent-solvent
attraction is
broken up; requires energy
 Solute-solvent
attraction is
formed; releases enerty

 Molarity
= Moles of Solute
Liters of Solution
 No
charged particles are present
and they are not mobile
 Heterogeneous
