Question

identify five techniques that take advantage of different physical properties in order to separate mixtures and describe how each is done. technique 1: how it is done: technique 2: how it is done: technique 3: how it is done: technique 4: how it is done: technique 5: how it is done: science notebook - matter—properties and changes 38

Explanation:

1. Filtration: Separates solid - liquid mixtures. A filter paper is used, and the liquid passes through while the solid is retained due to the difference in particle size.
2. Evaporation: Used for separating a soluble solid from a liquid. The mixture is heated, the liquid evaporates, and the solid is left behind as it has a much higher boiling point.
3. Distillation: Separates mixtures of liquids with different boiling points. The mixture is heated to vaporize the component with the lower boiling point, which is then condensed and collected.
4. Magnetic separation: Separates magnetic materials from non - magnetic ones. A magnet is used to attract the magnetic substances in the mixture.
5. Chromatography: Separates components of a mixture based on their different solubilities in a solvent and different rates of movement through a stationary phase.

Answer:

Technique 1: Filtration
How it is done: Use a filter paper. Liquid passes through, solid is retained.
Technique 2: Evaporation
How it is done: Heat the mixture, liquid evaporates, solid remains.
Technique 3: Distillation
How it is done: Heat the liquid mixture, vaporize the lower - boiling component, then condense it.
Technique 4: Magnetic separation
How it is done: Use a magnet to attract magnetic substances.
Technique 5: Chromatography
How it is done: Based on different solubilities and movement rates through a stationary phase.
