What is a Mixture?

• A substance formed from a two or more elements held by chemical bonds

• A mixture of elements or compounds which can be physically separated

Which one is Filtration?

• Used if the product is an insoluble solid and needs to be separated from a liquid. Uses filter paper

• Used if the product is a soluble solid. Its placed in an evaporating basin and heated until crystals form

• Used if the product is a soluble solid. Its placed in an evaporating basin and heated until start crystals forming then the heat is removed letting the crystals form while cool. Its then Filtered out

Which one is Evaporation?
