Comparing Mixtures and Compounds

Mixtures Compounds

Made of 2 or more substances Made of 2 or more substances physically combined chemically combined Substances keep their own properties Substances lose their own properties

Can be separated by physical means Can be separated only by chemical means Have no definite Have a definite chemical composition

What method is used to separate mixtures Ways to physically separate a based on – uses point? • – uses magnetism What method is used • Centrifuge – uses to separate mixtures based on density? • Filtering – separates large from smaller ones What method is used There are 2 types of mixtures: to separate mixtures (1) Heterogeneous Mixtures: the parts mixed together can still be based on size? distinguished from one another...NOT uniform in composition Give examples of a heterogeneous Examples: chicken soup, fruit salad, dirt, in mixture

Mixtures 12 (2) Homogenous Mixtures: the parts mixed together cannot be distinguished from one another...completely uniform in composition. Give examples of a homogenous Examples: Air, Kool-aid, Brass, salt water, mixture

Differentiate Types of Homogenous mixtures between a homogenous 1. Suspensions mixture and a  i.e. chocolate milk, muddy water, Italian heterogeneous mixture.  They are cloudy (usually a mixed with small

particles) Identify an example of a suspension.  Needs to be shaken or stirred to keep the from Will the solid settling particles settle in a

suspension?  The solids can be filtered out 2. Colloid Can the solid particles in a  i.e. milk, Mt. Dew, ranch dressing suspension be filtered?

 They are cloudy Give an example of a colloid.  The particles are evenly spread out Give an example of a colloid.  Cannot filter solid particles easily Will the solid 3. Solution particles settle in a  i.e. sprite, air, salt water, honey colloid?

Can the solid  The mixture is clear particles in a colloid be filtered?  The particles dissolve in the fluid; they become so small that they cannot be seen Give an example of a solution.

 A solution does not Will the solid separate particles settle in a solution? out by letting it Can the solid stand or by particles in a filtering solution be filtered?

 The particles are evenly spread out
