Mixture & Separation Sort

Chemistry Area 1 SHOULD DO 3 • classify + separate

Part 1 — Classify each mixture
Uniform + clear = solution; uniform but scatters light and never settles = colloid; particles settle = suspension; two separate layers = heterogeneous.
Salt dissolved in water
Milk
Sand in water
Fog (tiny water droplets in air)
Sparkling water
Gelatin dessert
Oil and water (separated)
Whole-blood sample
Solution
Colloid
Suspension
Heterogeneous (2 phases)
Part 2 — Match each mixture to its separation technique
Filtration = particle size; evaporation/distillation = boiling point; decanting = density; a truly uniform mixture cannot be undone by these methods.
Sand in water
Salt dissolved in water
Fog
Sparkling water
Oil over water
Filtration
Evaporation or distillation
None (it is uniform)
Decanting
