Separation Techniques key idea
Material
The substance or sample being studied.Property
For sand and water, sand is insoluble and has larger particles, so filtration works. For salt solution, salt is dissolved, so evaporation is needed.Evidence
The visible observation, label, or test result.Conclusion
The chemistry idea shown by the evidence.Labelled diagram
Separation Techniques explain card
A mixture can be separated when its components have different properties. The method must match the property difference.Exam cue: Use a labelled observation before the explanation.
- 1Material -> Property: has
- 2Evidence -> Conclusion: supports
