- Adjective: Filtered
About Filtering
- Filtering cannot separate anything dissolved in a liquid.
- When you filter the solid will get stuck in the filter paper and the liquid will pass through.
Examples
 |
You can separate mud from water in the puddle with filter paper and a funnel. |  |
Key Stage 3
Meaning
Filtration is the process of separating a mixture of a liquid and an insoluble solid.
About Filtering
- Only insoluble solids can be separated by filtering.
- Filtering uses a filter that has very small holes in it that allow the particles in the liquid through, but not the lumps of solid.
