2
Classification of Matter
3
Heterogeneous Mixtures

• see visibly different regions
• granite
• dirt
• cereals
• oil vinegar
• see a boundary
• ice cubes in water

4
Homogeneous Mixtures

• particles very small on atomic scale
• too small to be seen
• cant be sorted or trapped by filter
• wont scatter light
• particles evenly distributed
• mixture will not separate

5
Solution

• homogeneous mixture of 2 or more substances in a
  single physical state (phase)

6
Parts of a Solution

• solute substance being
• dissolved
• solvent dispersing medium
• substance being dissolved in

7
Can you identify the solute and solvent in each
picture?

9
hints to identify solute solvent

• solute
• substance that changes phase
• substance that have less of
• solvent
• substance that maintains phase
• substance that have more of

10
Aqueous Solutions

• water is solvent
• transition metals form brightly colored solutions

11
Solutions occur in all 3 phases!

Gas in a liquidCO2 in and out of water
bubbles mean its a mixture not a solution!
