Lesson details
Key learning points
- Filtration is a technique used to separate insoluble substances from a mixture with a liquid.
- Separation in filtration occurs due to the difference in size of particles.
- The terms 'filtrate' and 'residue' describe the components separated by the process of filtration.
Keywords
Filtration - Filtration is a technique to separate insoluble solids from a liquid by passing the mixture it is in through a filter.
Filtrate - A filtrate is the liquid component separated from a mixture as a result of filtration.
Residue - The insoluble component collected in the filter paper as a result of filtration is called the residue.
Component - A component refers to a part of something, e.g. a tyre on a car.
Common misconception
A funnel is the same as a filter.
A funnel streamlines movement, while a filter separates materials. Use everyday examples to highlight the difference, e.g. an oil funnel vs. an oil filter, or a coffee funnel vs. a coffee filter.
