Separating mixtures

Hi, in this post I'm going to talk about the methods we have seen in the laboratory and the objects we used
- Filings Very small pieces of metal made when the metal is filed
-Funnel They are used to filter metals
-Beaker They are used for calculate the volume of liquids
-Pore A very small hole
-Boiling point The temperature in a substance melts
- Crystallization The process in which a liquid transform in crystals

Methods for Separating mixtures

-Magnetic separation
This method it only can be used when one of the components has magnetic properties and the others don't

-Decantation
We use for liquids with different densities that don't mix together

-Filtration
We use this method to separate a solid from a liquid that hasn't dissolved like sand and water

-Distillation
We use distillation to separate soluble liquids with very different boiling
points from each others

-Evaporation and Crystallization
We use this method to separate a solid dissolved in a liquid

-Cromatography
We use this to separate two components In a mixture according to how soluble they are in a particular solvent
