Chemistry-Seperation techiniques Flashcards
to revise
Define
Pure
Something made of only one element/compound
Define
Substance
A type of matter/material , with specific propeties and characteristics
Define
Mixture
A combination of two or more substances, that have not reacted
Define
Compound
A combination of two or more substances that have reacted
Define
Filtration
A technique is used to separate an insouluble solute from a solution, via passing the solution through a filter. It can be used to obtain a product that is free from unreacted chemicals.
Define
Filter
A porous device used to remove impurities or solid particles from a liquid/gas that passes through it.
Define
Solute
A substance which dissolves into a solvent
Define
Solvent
A substance in which the solute dissolves into.
Define
Solution
The product of the solute dissolving into the solvent
Define
Evaporation
A techinique to separate a dissolved, solid solute from its solution via evaporating/boiling it’s liquid solvent to a smaller volume, and then allowing the solute to form crystals.
Define
Distillation
A techinique used to seperate a solvent from it’s solution via changing it’s state to a more collectable one
Define
Magnetic seperation
A techinique used to seperate a mangnetic solute , from it’s solvent, via a magnet
Define
Tweezing
A techinque used to seperate unnissolved solid solutes from a solvent, via the use of tweezers
Define
Chromatography
A technique used to seperate two liquids of different solubility, via seeing how for they can dissolve into H2O
Define
Centifuge
A technique, used to seperate substances based on their density, via spinning the solution at high speeds, until the densest come to the ends due to centrifugal force
