TOPIC: Methods of Separating Mixtures Essential Question: What are the different ways of separating mixture? Chemistry

What are the ways of separating Mixture? a. ) Filtration b. ) Centrifuge c. ) Decanting d. ) Chromatography e. ) Distillation f. ) Density

Filtration can be used to separate an insoluble substance from a soluble substance Ex. Coffee grounds are separated by water through filtration

Centrifuge • A centrifuge is a tool used to separate matter of different densities. • The centrifuge spins rapidly. • Ex. Separation of solid matter in blood from the liquid portion.

Decant • To decant – pour the liquids off and leave the solids behind

Chromatography • Used to separate components of a solution • Ex. Paper chromatography separate black into the colored dyes it contains

Distillation • A method of separating substances that have different boiling points • Ex. Separating alcohol from water • Boiling pt of alcohol is 70 Celcius • Boiling pt of water is 100 Celcius

Density • Ratio of mass and volume

Update Notebook • Paste or tape that notes on page 35 • On page 34 You are going to draw all of those techniques in separating the mixtures

Evaporation can be used to separate a solute from the solvent in a solution

A magnet • Can be used to separate a magnetic substance from a non-magnetic substance
