The document outlines the differences between compounds and mixtures, defining key terms and providing examples. It explains separation methods including filtration, distillation, and chromatography, highlighting their processes and common uses. The document concludes with an exercise for students to identify appropriate separation techniques for specific scenarios.

1. AIM: HOW TO SEPARATE
MIXTURES
DO NOW: EXPLAIN THE DIFFERENCE BETWEEN A COMPOUND AND A MIXTURE.
GIVE ONE EXAMPLE OF A COMPOUND AND ONE EXAMPLE OF A MIXTURE
HOMEWORK: ON A SEPARATE SHEET, PICK ONE SEPARATION METHOD,
EXPLAIN THE PROCESS, AND INCLUDE DRAWING.

4. WHAT IS THE DIFFERENCE BETWEEN A
HOMOGENEOUS AND A HETEROGENEOUS
MIXTURE?
HOMOGENEOUS HETEROGENEOUS

5. VOCAB
• MISCIBLE – CAPABLE OF BEING MIXED
• IMMISCIBLE – CANNOT BE MIXED
• SOLUBLE – ABLE TO BE DISSOLVED
• INSOLUBLE – UNABLE TO BE DISSOLVED

6. WHAT IS A SOLUTION?
• ANOTHER WORD FOR HOMOGENEOUS MIXTURE
• PARTS OF A SOLUTION
• SOLVENT
• SOLUTE
• SOLVENT DISSOLVES THE SOLUTE; SOLUTE IS WHAT IS BEING
DISSOLVED.

7. WHAT IS AN AQUEOUS SOLUTION?
• AN AQUEOUS SOLUTION IS A SOLUTION IN WHICH
WATER IS THE SOLVENT ( A SUBSTANCE IS DISSOLVED
IN WATER)
• CREATED BY DISSOLVING SUBSTANCE IN WATER
• (AQ) NEXT TO A SUBSTANCE MEANS DISSOLVED IN
WATER

9. METHODS TO SEPARATING MIXTURES
• ON THE FOLLOWING SLIDES, WE WILL
INVESTIGATE THREE METHODS TO SEPARATING
MIXTURES
• FOR EACH METHOD YOU WILL TURN TO YOU
PARTNER, DISCUSS AND WRITE DOWN WHAT
YOU SEE AND EXPLAIN HOW YOU THINK THE
SEPARATION OCCURS

10. FILTRATION
• FILTRATION IS A SEPARATION
METHOD USED TO SEPARATE
OUT PURE SUBSTANCES IN
MIXTURES MADE UP OF
PARTICLES SOME OF WHICH
ARE TOO LARGE ENOUGH IN
SIZE TO PASS THROUGH THE
FILTER

11. COMMON USE OF FILTERS
• AIR CONDITIONERS
HAVE FILTERS THAT
ALLOW THE AIR TO
PASS THROUGH
WHILE TRAPPING
SOLIDS SUCH AS
LINT AND DUST

12. DISTILLATION
• WATER BOILS AT 100 OC
• ETHANOL BOILS AT 74.4 OC
• DISTILLATION IS A
PROCEDURE BY WHICH A
SOLID AND A LIQUID, OR
TWO LIQUIDS WITH
DIFFERENT BOILING POINTS
CAN BE SEPARATED.
• USES THE PROCESS OF
EVAPORATION AND
CONDENSATION.

13. COMMON USE OF
DISTILLATION
• GASOLINE IS
OBTAINED FROM
CRUDE OIL BY
THE PROCESS OF
DISTILLATION

14. CHROMATOGRAPHY
• THE COMPONENTS IN
THE MIXTURE HAVE
DIFFERENT
ATTRACTIONS WITH THE
CHROMATOGRAPHY
PAPER; THEREFORE, THE
DIFFERENT
COMPONENTS TRAVEL

15. COMMON USES OF CHROMATOGRAPHY
• WELL, IN REAL LIFE, GAS
CHROMATOGRAPHY IS OFTEN USED TO
INVESTIGATE CRIMINAL CASES LIKE THE
ONES FEATURED ON THOSE SHOWS.
• THIS CAN TAKE THE FORM OF CRIME
SCENE TESTING (THE ANALYSIS OF
BLOOD OR CLOTH SAMPLES), ARSON
VERIFICATION (IDENTIFYING THE
CHEMICALS RESPONSIBLE FOR A FIRE
TO SEE WHETHER THERE WAS FOUL
PLAY) OR BLOOD TESTING AFTER DEATH
TO DETERMINE LEVELS OF ALCOHOL,

16. ON A SEPARATE SHEET OF PAPER TO BE
COLLECTED, NAME THE TECHNIQUES WHICH ARE
SUITABLE FOR SEPARATING THE FOLLOWING
MIXTURE:
Situation Separation Technique
a. To obtain drinking water from muddy
water
b. To separate gasoline from crude oil
c. To remove leaves from a swimming pool
d. To obtain pure sugar from a solution
e. To determine whether the coloring in a
fruit juice is a single substance or a
