Mixture

Poll

Do you believe you can easily separate the Hydrogen Atoms from the Oxygen Atoms?

• Yes

• No

Why do you believe that it is difficult to separate the hydrogen molecule from the Oxygen molecules in water?

Water molecule cannot be separated physically by ordinary means but CHEMICALLY hrough a process called HYDROLYSIS

​

​

Can you separate the nuts from the M&M in a TrailMix?

You could separate the nuts from the M&M because they were a mixture and were not chemically combined

​Objectives

1. What is a mixture ?

2. How are Mixtures different from Compounds ?

3. What is a solution ?

4. How can the differnt components in a Mixture or compound be Separated?

What is a Mixture ?

​A mixture is matter made up of two or more substances that are combined physically (mixed together).

Substances in a mixture do not change or combine chemically.

Substances keep their own properties

Homogenous Mixture

Heterogenous Mixture

​

​

There are 2 types of mixtures

Heterogenous Mixture

Heterogenous Mixture

• A mixture where the different compounds and or elements are not UNIFORMLY mixed are called HETEROGENOUS mixture

• The parts can be easily seen. 

Homogenous Mixture

• A mixture where the elements or compounds are UNIFORMILY mixed it is said to be HOMOGENOUS

• The different compounds or elements cannot be differentiated (seen).

• SOLUTION, where a SOLUTE is dissolved in SOLVENT is a HOMOGENOUS MIXTURE

• ​ SOLUTE is what is being dissolved

• ​ SOLVENT is what is doing the dissolving

• ​ In a sugar solution water is the solvent while sugar is the solute

• ​ Water is called the UNIVERSAL SOLVENT because it is used to dissolve most things
