Adsorbtion
This is a separation method that makes the diff in adhesion of substances to an adsorption agent
What is a well known adsorption agent
Charcoal
Chromatography
Separation method that uses the diff in adhesion to the stationary phase and solubility in the mobile phase
What is the RF value in gas’s
Retention time
RF value
Indicates how far a substance is transported by the mobile phase
What is the result of chromatography
Chromatogram
Content
The content of a substance in a solution is given in grams per liter
Distillation
Separation method in which you boil a solution of a solid substance or a mix of liquids
What is the method distillation based on
Diff in boiling point
What is the the liquid with the lowest boiling point called
Distillate
What is the substance left behind in a distillation flask called
Residue
What kind of separation method is evaporation
Separate solute from liquid
What method is evaporation based on
Diff in boiling point
Extraction
Separation method in which part of a mixture dissolves in a solvent and other substances don’t
What method is extraction based on
Diff in solubility
What is the extraction agent
A liquid used for extraction
Filtration
Separation method for suspensions a mixture passes though a filter
What is the method filtration based on
Diff in particle size
What is the filtrate
That’s whatever passed through the filter
What is the residue in filtration
Whatever’s stuck on the filter after filtration
What is mass percentage
Mass of substance in grams pers 100 grams of the mixture
Volume percentage
Volume of substance in mL per 100mL of the mixture
What’s the diff between mass and volume
Mass is in grams
Volume is in mL
Percentage yield
The ratio of actual yield and theoretical yield
