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
