Purpose: The objective is to separate the heterogeneous mixture of salt, iron filings, and salt into each pure form using filtration, evaporation, and magnetism.
Background:
When separating a mixture, preferably to separate a mixture that includes a soluble liquid and a insoluble solid, filtration is the best because solid molecules are bigger than liquid molecules. A filter contains pores that are small enough to let small partials though the pores while holding back the larger particles. Magnetism is ideal for separating mixtures of two solids with one part having magnetic properties. Metals like iron have magnetic properties that is used to separate from different materials. Evaporation is applied when separating a soluble solid and a solvent. Heating the solvent will cause it to evaporate and leave the soluble solid behind because it needs more heat to reach its boiling point. …show more content…
1. Sand and water: Sand and water could separate by dilution because water has an evaporating point of 100˚C, while the sand’s melting point is at 1650˚C.
2. Sugar and water: Sugar is similar to salt as both are soluble crystals and would easily be separated by distillation because the evaporating point of water is 100˚C and the melting point of sugar is 180˚C.
3. Oil and water: Oil and water can be separated by distillation because the boiling point of water is 100˚C and oil has boiling point of 300˚C.
4. Sand and gravel: To separate sand gravel is. to use a sifter and have a mesh with a size of the holes between the diameter of the sand and gravel. The larger particle is caught by the mesh and the smaller passes through the pores.
5. A mixture of heptane and heptanol: The boiling point of heptane is 98˚C and 176˚C for heptanol. The best method for separation is with distillation evaporating the lower temperature liquid and condense in another
