Distilled water Pure
Heterogeneous Mixture- A mixture where
the components are visibly distinguishable
More than one PHASE – distinct layer with a
uniform composition. Phases can be
Colloid – suspended particles are too small to
settle out. (Tyndall Effect)
Suspension – Suspended
particles in this mixture will
Oil and water – 2 phases
Salad dressing – water and
vinegar = phase 1, oil = phase 2,
seasoning = phase 3
Filtration – separates a solid from a
liquid by collecting the solid in a
funnel and allowing the liquid to drain
through the funnel into a flask.
Sand and water
Centrifugation – Separates particles
in a mixture by particle size and
Centrifugation – Blood is a
Homogeneous Mixture- A mixture where the
components are spread evenly throughout.
Solvent – dissolving fluid
Solute – substance that is dissolved
Solution – Another name for a
Solvation – the process
where solvent molecules
surround solute molecules.
Volumes are not additive
Water and alcohol
Koolaid (water and sugar)
(Alloys are homogeneous mixtures of metals!)
Distillation/Evaporationboiling off the solvent.
The solute remains in the
What happens to alcohols’ solubility in water as the hydrocarbon
portion of the alcohol molecules gets longer?
Water – Ethanol Interactions
Dissolving a solute in a solvent is favored when the interactions
between the solute and solvent molecules are stronger
than the solvent-solvent and solute-solute interactions.
Gold is an alloy
