Method to Separate a Mixture
|
|
| |
- The are various methods that we can use to separate a mixture.
|
| |
- Methods to separate a mixture:-
|
| |
| 1. |
|
Handpicking |
| |
|
- To separate two big-sized materials. |
| |
|
|
| 2. |
|
Sieving |
| |
|
- To separate fine-sized materials and large-sized materials. |
| |
|
|
| 3. |
|
Separate mixture using a magnet |
| |
|
- To separate a mixture that can be attracted by a magnet. |
| |
|
|
| 4. |
|
Floatation |
| |
|
- To separate materials that can float from materials that sink. |
| |
|
|
| 5. |
|
Filtration |
| |
|
- To separate solid materials from liquid material |
|
| |
|

Soluble and Insoluble Materials
|
|
| |
- Some materials can dissolve in water such as salt and sugar.
|
| |
- Some materials cannot dissolve in water such as stone, beans and sand.
|

| Materials that dissolve in water |

Materials that Dissolve More Quickly
|
|
| |
- The solubility of the materials is affected by the temperature of the water, the size of materials and the stirring.
|
| |
| The temperature of the water |
 |
|
The hotter the liquid the faster the materials will dissolve.
The substance will dissolve slower in cold water.
|
|
| |
| Size of the substance |
 |
|
The larger the size of the materials, the slower the materials will dissolve.
Smaller size substance will have a faster rate of solubility.
|
|
| |
| Stirring |
 |
|
The substance that is stirred when mixed in the liquid will dissolve faster than unstirred substances.
