Study Notes
Components of Mixtures
- Most materials in nature are mixtures whose components can be separated using various methods.
- Seawater is a mixture comprised of salt and water, which can be separated through evaporation.
Separating Homogeneous Mixtures
- Homogeneous mixtures have their components evenly dispersed, making identification difficult.
Separation by Evaporation
- Salt can be obtained from seawater by allowing the water to evaporate.
- Demonstration of evaporation: Place a dish of saltwater atop a container of water; the water evaporates and condenses on the container, leaving salt behind.
Separation by Centrifugation
- Obtaining sugar from sugar cane juice involves centrifugation, which is a more complex process than separating salt from seawater.
- A centrifuge spins tubes at high speeds, effectively separating different substances within.
Separating by Distillation
- Ethanol is produced through the distillation of plant extracts, notably from sugarcane.
- The distillation process involves dissolving sugars in water, allowing for the extraction of materials from the mixture.
