TRANSCRIPT
CHAPTER 9: LESSON 4
How are mixtures formed and separated
MIXTURES A mix of 2 or more substances. Example 1: Salt and sand. Example 2: Salt and water. Example 3: Salad
TYPES OF MIXTURE:
Suspensions Solutions
SUSPENSIONS Type of mixture which over time has
one or more parts that settles to the bottom.
Example 1: Sand in water mixture. Example 2: Orange juice. Example 3: Some medicines.
SOLUTIONS Type of mixture with parts that blends
so that it looks the same everywhere even under the microscope.
Example: Salt in water mixture .
SOLUTIONS
Solutes Solvents
The smaller amount that is dissolved
in a solution.
The larger amount that dissolves the
other substance in a
solution.
Note: Solutions can be made with solids,
liquids and gases. Example: Sugar (solute) in water
(solvent).
SOLUBILITY What is solubility? Amount of solute that can dissolve in a
solvent. Note: Water is a universal solvent. Many substances become more soluble
at higher temperatures.
SEPARATING MIXTURES
Filtration
Evaporation
Magnet Distillation
FILTRATION Using filter paper. Example: Separating sand in water
mixture. Sand Stays in filter
paper. Water passes through.
EVAPORATION Example: Separating sugar in water
mixture. Water Evaporates. Sugar Stays behind.
MAGNET Example: Separating sand in iron
mixture. Iron Attracted. Sand Stays behind.
DISTILLATION Separating mixture of liquids.
