_______ Is the measure of how much solute will dissolve in a solvent.

• Solubility

• Saturation

• Suspension

• Colloid

By observing the ____________ in solutions you can effectively determine the best way to separate them.

• Solubility

• Properties of matter

• Density

• Composition

A soil sample is collected. It has high concentrations of Iron (Fe) in the mixture. Which is the best way to separate the iron from this mixture.

• Using a magnet because the clay and dirt will stick to it.

• Using a magnet because iron has a magnetic property.

• Lighting the soil on fire because Iron is combustible and will burn but the rest will not.

• Using a filter to separate the gravel from the smaller pieces where the highest iron concentration is.

After a storm, large amounts of debris gathered on the coast line. The debris all had a combustible property which allowed environmentalist to come up with the following plan of separation.

• Use a net to scrape across the beach ground. This will filter out the debris.

• Set a controlled fire to remove the debris.

• Hand pick all the debris since they are large enough to.

• Use a magnet to remove the debris.
