This document provides information about different types of matter and mixtures. It defines matter as either a pure substance or a mixture. Pure substances are either elements, which are composed of identical atoms, or compounds, which are composed of two or more elements in a fixed ratio. Mixtures can be either homogeneous, consisting of evenly distributed components like solutions, or heterogeneous with unevenly distributed components like suspensions. Common examples are provided like salt, water and soda for pure substances and milk, fog and paint for mixtures.

5. Pure Substances
 Matter:
 Matter is classified as substances or a mixture
of substances.
 Substance:
 A pure substance, or simply a substance, is a
type of matter with a fixed composition
 A substance can be either an element or a
compound.

6. Pure Substances
 Element
 matter composed of identical atoms
 EX: copper, gold, lead

7. Compounds
 Can you imagine yourself putting something
made from a slivery metal and a greenish-
yellow, poisonous gas on your food?

8. Compounds
 Table salt is a chemical
compound that fits this
description.
 Even though it looks like white
crystals and adds flavor to
food, its components—sodium
and chlorine—are neither white
nor salty.

9. Pure Substances
 Compound
 matter composed of 2 or more
elements in a fixed ratio
 Cannot be separated by a
physical means
 properties differ from those of
individual elements
 EX: salt (NaCl), water, chalk

10. o A mixture, such as
the pizza or soft
drink shown, is a
material made up of
two or more
substances that
can be easily
separated by
physical means.
Mixtures

11. Mixtures
 Variable combination of 2 or more pure
substances.
Homogeneous Mixture (Solution)
even distribution of components
very small particles
particles never settle
EX: saline solution, fresh pickle juice,
vinegar, soda

12. Heterogeneous Mixtures
 Unlike compounds, mixtures do not always
contain the same proportions of the
substances that make them up.
 A mixture in which different materials can be
distinguished easily is called a heterogeneous
mixture.

13. Mixtures
 Heterogeneous Mixture
 uneven distribution of components
 colloids and suspensions
 EX: granite, permanent press fabric

14. Colloids
 Milk is an example of a specific kind of mixture
called a colloid.
 A colloid is a type of mixture with particles that
are larger than those in solutions but not
heavy enough to settle out.

15. Mixtures
 Colloid
 medium-sized particles
 Tyndall effect - particles scatter light
(looks cloudy)
 particles never settle
 EX: milk, fog, gelatin, paint,

16. Tyndall Effect
Because of
the Tyndall
effect, A light
beam is
Scattered by
the Colloid
suspension
On the left, but
Passes
invisibly
Through the
solution
On the right.

17. Mixtures
 Suspension
 large particles
 particles scatter light
 particles will settle
(needs to be shaken)
 EX: Italian salad dressing (oil,
vinegar, and spices), a river delta,
pond

18. Suspensions
• The table summarizes the properties of
different types of mixtures.
