Properties of Mixtures
• A mixture is a combination of two or
more substances that are not
chemically combined.
• Each substance in a mixture keeps its
identity because no chemical change
happens when a mixture is made.
3. Section 3 MixturesChapter 5
Properties of Mixtures,
• Mixtures can be separated by physical
means, such as filtration, evaporation,
and distillation.
• The components of a mixture do not
need to be mixed in a definite ratio.
5. Section 3 MixturesChapter 5
Solutions
• A solution appears to be a single
substance, but it is actually a
homogeneous mixture composed of
particles of two or more substances that
are distributed evenly among each
other.
• In solutions, the solute is the substance
that is dissolved. The solvent is the
substance in which the solute is
dissolved.
6. Section 3 MixturesChapter 5
Solutions, continued
• A substance that is insoluble, or unable
to dissolve, forms a mixture that is not a
solution.
• Solutions may be liquids, gases, or
solids.
• Alloys are solid solutions in which
metals or nonmetals are dissolved in
other metals.
