Study Notes
Mixtures and Separation Techniques
- Sand and salt form mixtures with water, but their separation methods differ.
- Sand can be separated from water through filtration, while salt cannot due to its soluble nature.
Separation Methods
- Various techniques exist to separate components of a mixture:
- Filtration: Effective for solids with small particles.
- Sieving: Used for separating solids of different sizes or large particles mixed with liquids.
- Dissolving, evaporating, decanting, and using magnets are other methods employed for separation.
Picking
- Some mixtures, like seeds (e.g., atis, squash, mung beans, corn), can be separated manually by picking.
- Key properties aiding in manual separation include color and particle size.
Filtering
- Filtration involves separating small solid particles from liquids using a filtering material (e.g., cloth, filter paper).
- The filtering material captures solid particles, allowing the liquid to pass through.
Sieving
- Sieving separates solids of different sizes using sieves or strainers.
- The mixture is placed on a sieve, which retains larger particles while permitting smaller particles or liquids to go through.
