Separation of Mixtures
A. Magnetic Attraction
Separating mixtures containing magnetic material like iron, cobalt, and nickel
B. Separating Funnel
A mixture of two immiscible liquids can be separated using a separating funnel
immiscible means that the liquids don't dissolve in each other, example: oil and water
C. Decantation
Decantation is a process to separate mixtures by removing a liquid layer that is free of a precipitate, or the solids deposited from a solution
Example:
Sand can be separated from sand water mixture
D. Filtration
Separating mixture of un-dissolved solids from a liquid
E. Evaporation
Separating mixture of dissolved solids from a liquid
F. Distillation
1. Simple Distillation
Simple distillation is a method for separating the solvent from a solution
Example:
Water can be separated from salt solution
This method works because water has a much lower boiling point than salt
2. Fractional Distillation
Fractional distillation is a method for separating a liquid from a mixture of two or more liquids
Example:
Separating crude oil
