This document defines and describes mixtures and solutions. It states that a mixture is made of two or more substances that are not chemically combined and can exist as solids, liquids, gases, or combinations. Mixtures are either heterogeneous, where the phases can be seen, or homogeneous, where they cannot. A solution is a special type of homogeneous mixture containing a solute dissolved in a solvent. It discusses how to make solutions by dissolving a solute in a solvent, and defines concepts like solubility, dilute vs concentrated solutions, saturated solutions, and super-saturated solutions.

2. A mixture is made of 2 or more types of atoms
that are NOT chemically combined together.
Mixtures can take many forms:
2+ Solids 2+ Gases

6. Types Of MixturesTypes Of Mixtures
There are 2 major types of mixtures:
Heterogeneous Homogeneous
You can see the
different parts
(phases) of the
mixture easily
Means “different” Means “the same”
You cannot see
the different parts
(phases) of the
mixture

10. A solution is a special type of mixture.
SolutionsSolutions
A solution is a homogeneous mixture
that combines a solute and a solvent.
A solution involves one
substance dissolving in
another substance, which
is usually a liquid.

11. A solution is a special type of mixture.
SolutionsSolutions
A solution is a homogeneous mixture
that combines a solute and a solvent.
The solid part that
gets dissolved.
e.g. salt, sugar
The liquid part that
does the dissolving.
e.g. water

14. We can measure how easily a solute
will dissolve in a certain solvent.
SolubilitySolubility
This measurement is called solubility.
The solute dissolves
quickly & easily
e.g. salt in water
The solute does not
dissolve easily
e.g. sand in water
HIGH Solubility LOW Solubility

15. We can add a LITTLE or a LOT of solute!
Dilute vs. ConcentratedDilute vs. Concentrated
For example, putting spoonfuls
of sugar into a cup of tea…
A solution with only
a small amount
of solute is called
a dilute solution.

For example, putting spoonfuls

A solution with a
large amount of
solute is called
concentrated.

17. Eventually, a solvent can’t hold anymore!
Saturated SolutionsSaturated Solutions
A saturated solution CANNOT hold any
more solute at a certain temperature.

18. But, by heating a solvent up, we can make
it hold even more solute than normal.
A super-saturated solution contains more
solute than it can normally dissolve.

Heat It!
