Study Notes
Sedimentation and Decantation
- Sedimentation involves allowing insoluble solids, known as sediments, to settle at the bottom of a liquid container.
- Decantation is the process of slowly transferring liquid from a container without disturbing settled sediments.
- Example of decantation: pouring water from a sand-water mixture, leaving the sand behind.
- Common practical applications of decantation include washing rice, where water is poured out while retaining rice grains.
- Separating immiscible liquids, such as oil and water, can be accomplished via decantation since oil floats on water.
- Laboratory separation funnels can aid in efficiently separating immiscible liquids.
Filtration
- Filtration is a method used to separate components of suspension mixtures using a filter.
- A filter consists of a porous mesh of fibers, allowing liquids (like water) to pass through while trapping impurities and solids.
- The liquid that successfully passes through the filter is known as filtrate, while the trapped solids are referred to as residue.
- Filtration is commonly utilized to remove unwanted particles from liquids, such as purifying water for personal or business purposes.
- Typical contaminants trapped during filtration include dirt and sand, which do not pass through the filter.
