3-Solutions
Solution: The differences between a solution and a
pure
substance can only be discovered by looking at the molecules or atoms.
As an
example to compare this, you can use hydrogen (pure substance) and air
(mixture
of 80% nitrogen, 19% oxygen, and 1% of other gasses). Both are
colorless
gasses at room temperature, and are quite unlike a mechanical mixture
or
suspension, but are completely different. A solution is a mixture that
looks
like a pure substance without the joined molecules, (there is only one
kind of
molecule thought pure substance), and does not separate over time. An
alloy is two or more metals that have been melted together and cooled
to from a solid solution.
Some examples are apple juice, tea, ink, air, wax, bronze, and
brass. It
doesn’t matter what the color is thought the solid, liquid, or gas; as
long as there
is only one that is consistent, otherwise it would be considered a
suspension or a mechanical mixture. Below is a glass of apple juice,
a wax candle,
and a package of gum, all examples of a solution.
