What is solubility?

• different materials placed together but keeping their own properties

• a mixture in which substances spread out evenly and will not settle

• the substance in a solution that has the greatest amount

• the substance in a solution that has the least amount

Which process would you use to separate solid particles from larger particles in a mixture with filter paper in a funnel to trap solids so that the liquids will pass through.
