Hello class, class (yes, yes)
As you know we are learning about mixtures separation. Watch these videos to learn about all of them.
DISTILATION
When two liquids have different boiling temperatures (diferentes puntos de ebullición, que es como se llama a la temperatura a las que hierven) we can DESTILATE THEM:
- we boil the mixture
- one of the substances evaporates and travels through a condenser
- the evaporated substance condenses and becomes liquid again
DECANTATION
In a mixture of liquid and solid, the solid usually settle down at the bottom (el sólido se hunde al fondo del bote) this is called sedimentation. Decantation is the process of pouring out the liquid or water (which contains the dust or soil particles) without disturbing the sediment.
FILTRATION
Sometimes particles are very small and we cannot separate all of them. Using a filter we can filtrate small particles. This is what we do when we wear a mask to go to the supermarket.
MAGNETIC SEPARATION
We can separate metal and non-metal materials in a mixture using magnets
EVAPORATION
We can separate a solid from a liquid through evaporation: We heat the mixture and the liquid evaporates leaving the solid.
evaporation is used to make salt
