Separation of Mixtures

Identify the different ways of separating mixtures.

Determine how the different ways are used to separate mixtures.

Identify the ways in which magnetic attraction, filtration, evaporation, distillation and paper chromatography can be used in daily life.

Separation of Mixtures

Mixtures are matter that are made up of two or more compounds and/or elements.

They can be easily separated. Suspensions and solutions are mixtures.

Separation of Mixtures

Magnetic Attraction

Separating mixtures containing magnetic material like iron, cobalt and nickel.

Separation of Mixtures

Evaporation

Separating mixture of dissolved solids from a liquid.

Heat is applied to quicken evaporation but NOT to cause decomposition.

Separation of Mixtures

Filtration

Separating mixture of un-dissolved solids from a liquid.

Some Filtration Systems

Separation of Mixtures

Distillation

Separating liquid-liquid mixtures of different boiling points.

Temperature tells the type of vapor that is entering the condenser.

Laboratory Distillation Setup

Stone chips are added into the liquid to allow

even and uniform boiling

Cold and hot water enters from the

bottom and top of the condenser

respectively. Water will gain heat as vapor condenses. Warmer

water is less effective in condensing vapor

Thermometer at the entrance of the condenser indicates the

boiling point of the type of

vapor entering it

Less Dense Component

Denser Component

(1) Mixtures added at the

base line

(2) Paper dipped into solvent for mixtures

(3) Component

will run along paper

as it dissolves in

solvent

Components of Essential Oils are separated

•Magnetic attraction to get iron filings

•Add water to dissolve salt

•Filter to get sand residue

•Evaporate filtrate to get salt

Separation of Mixtures

Conclusion 5 simple methods of separating mixtures. Different methods for components of

mixtures with different properties. Separating mixtures produces better

understanding of mixture. Man can produce useful

mixtures/components from raw components/mixtures.
