Mixtures & solutions Flashcards
A Mixture
is matter made up of two or more substances that keep their characteristics
A Mixture
Some mixtures can be easily separated by hand like paperclips and pencils.
Examples of Mixtures
Fruit salad, iron filings & sand, Rocks & sand , blocks, Nuts & Candy
A mixture
Other mixtures, require a tool in order to be separated. For example, if you want to separated noodles from water you must use a strainer to remove the water.
Mixtures
Mixtures of solids can be separated base properties (what we can see).
shape and size
mixtures can be separated by size, shape, texture, or color.
physical properties
Sometimes mixtures are not easy to separated and requires using physical properties such as: magnetism, boiling point, solubility, or density. Not only do we use physical properties to separate mixtures, many times this process requires using a tool.
How would you separate this mixture?
rocks and sand,
i would need to use a sieve or mesh screen
How would you separate this mixture?
blocks
I would use hand observable (what you can see). For example, by shape, size,
texture, or color.
How would you separate this mixture?
iron filings in sand or salt
by magnetism using a magnet
How would you separate this mixture?
water & sand
By filtration using a paper filter
How would you separate this mixture?
sand and cork
by using relative density less dense objects, such as the cork, will float and more dense objects, such as the sand, will sink
How would you separate this mixture?
Chex Mix
by hand using observable properties (what you can see). for example,
by shape, size, texture, or color.
How would you separate this mixture?
wood chips and iron nails
By magnetism using a magnet
How would you separate this mixture?
A salad
by hand using observable properties (what you can see). for example, by shape, size, texture, or color.
