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
The use of forceps eves, spoon, tweezers, and other similar tools. Applied in bigger
components of solid
Mechanical Separation
Which Swiss surgeon invented the forceps?
Emil Theodor Korcher
Process in which a substance is converted directly from a solid to a gas or from a gas to a solid without an intermediate liquid phase
Sublimation
Used for obtaining a compound in pure solid form of well-defined geometrically shaped crystals
Crystallization
