Mixtures and Solutions

Lesson 1

Classifying Mixtures and Solutions


What is a mixture

What is a Mixture?

  • A mixture is a combination of two or more different kinds of matter (solid, liquid, gas) or substances, each of which keeps its own physical properties.


What is a mixture1

What is a Mixture?

  • A substance is anything that contains only one kind of material. Examples would be sugar, water, iron filings

  • When you mix sugar with iron filings, you can easily see the two solids in the mixture.


Identifying mixtures

Identifying Mixtures

  • Homogenous Mixtures

    • A mixture in which the different substances are mixed evenly, and are too small to be seen.

    • No matter how long you let a powdered drink mix and water stand, like Kool-Aid, the evenly mixed particles that make up this homogenous mixture will not separate.

Identifying Mixtures

  • Heterogenous Mixtures

    • A mixture in which the different substances are mixed unevenly.

    • Many times you can see the different substances in the mixture. Examples would be: bread, chocolate milk, smoke and air, paper, sugar mixed with iron filings.


What is a solution

What is a Solution?

  • Sugar and Water

    • When you mix sugar and water, it’s not easy to tell what is in the mixture.

    • The sugar seems to disappear.

    • But if you taste it, you’ll find that the water is sweet. It is distributed evenly throughout the mixture.

    • When one substance dissolves in another, the two form a solution.

    • In other words, any mixture made up of tiny particles that are evenly mixed and do not settle out is called a solution.


What is a solution1

What is a Solution?

  • A solution is a specific type of mixture.

    • Are all solutions mixtures? Yes

    • Are all mixtures solutions? No

  • Solubility is the ability to be dissolved.

  • Sugar is soluble in water, but ground black pepper is not.
