Study Notes
Filtration
- Filtration separates insoluble solids from liquids.
- Water treatment plants use filtration to remove solid particles from river water, allowing only water to pass through the filter paper.
- Filter paper allows liquid to pass through, trapping solid particles. Solid particles are thus separated from the liquid.
Coagulation
- Coagulation uses additives to clump contaminants together.
- Clumped contaminants cannot pass through filters. The additives attract contaminants, causing them to clump together.
Solutions
- A solution is formed when a solute dissolves in a solvent.
- The solute is the smaller substance, being dissolved.
- The solvent is the larger substance, dissolving the solute.
- Sugar dissolving in tea creates a sugary tea solution.
