SEPARATING METHODS Flashcards
Allowing the dense, insoluble solid particles from a liquid mixture to settle down first then slowly pour the liquid to another container. Uses a separatory funnel to separate 2 or more immiscible fluids
Decantation
The process of separating the insoluble solid from the liquid substance by allowing the liquid to pass through a porous material
Filtration
Liquid to be filtered
Suspension
Liquid passed by the filter
Filtrate
Solid material remaining on the filter
Residue
4 General Types of Filtering Media:
- Granular Filters
- Felted Sheets
- Rigid, Porous Filters
- Filters composed of Semi-Permeable Membranes
Sand & crushed charcoal
Granular Filters
Paper/woven filters and cloth & wire mesh
Felted Sheet
Substances formed when brick or clay is fired at a low temperature
Rigid, Porous Filters
Employed for the separation of dispersed solid by dialysis.
Filters composed of Semi-Permeable Membranes
Use of magnets to separate the metallic from the non metallic
components of a mixture
Magnetism
Separates wanted elements from unwanted material
Sieving
Is a process that involves the evaporation and condensation of volatile liquid. The differences in boiling points among the substances in a homogenous mixture are frequently used as a basis for separating the mixture into its components.
Distillation
Used to separate the volatile oils from plant materials whether flower, leaves, bark, or roots
Steam Distillation
Used to separate a liquid mixture with a small range of boiling points
Fractional Distillation
