CHEMISTRY Flashcards
Intrinsic Property
Flammability
salt + water
homogeneous
particles settle over time
suspension
Large particles that do not settle
Colloid
larger particles than solution
colloid
Colloid
Dispersed phase:
Dispersion medium:
Fat
Water
scattering of light due to suspended particles
Tyndall effect
have larger particles and LESS STABLE
Suspension
separate salt and water
evaporation
separate sand and iron
magnetization
use of CONDENSER in distillation process
cool and condense vapor back to liquid
method use in differences in boiling point
Distillation
separate by solubility and mobility
chromatography
separate components with CLOSE boiling points
Fractional Distillation
