u Filtering can remove larger particles from the mixture.
u 3. How can you separate mixture with a magnetic property?
u You can use a magnet to attract the metals out.
u 4. If you have a solution such as salt and water in a solution, how could you separate them?
u You could evaporate the liquid out.

MIXTURE Tools:
Components and how they
are separated;
Sand and iron fillings

Muddy Water
Magnet-The magnet would attract the iron filling from the sand
Hot plate-As the water is heated it will evaporate leaving the salt behind.
Filter-As the water runs through the filter the larger particles will be trapped in the filter

What happens when you
raise the temperature of a
solvent?
What happens to the solubility of
Salt as temperature increases?
Why does temperature increase the
Solubility of solids?
What happens to gas as temperature
Increases?
The solute becomes more soluble as
Temperature increases.
Salt becomes more soluble as
temperature goes up.
The particles of the solvent move faster
Breaking up the solute.
The solubility decreases as temperature
Goes up.
Solubility and Temperature p. 342
uDraw Evidence Based on what you have
read and the data in the table, do you think
silver nitrate is a solid or a gas? Explain
uSilver nitrate is a solid because as
temperature rises it becomes more soluble.
At 0 C it is 122 but at 50 C it increase to
