Classification of Matter HETEROGENEOUS vs. HOMOGENEOUS

Classification of Matter Using the glossary in your book define the following words in your notes. Pure Substance Element Compound Solution Mixture Homogeneous Heterogeneous

Classification of Matter Heterogeneous Matter Homogeneous Matter Fluid mixtures Solid Mixture Pure Substances 4) Solutions 2) Colloids 3) Suspensions Aerosols emulsions 6) Compounds 5) Elements Gels

Classification of Matter Go to page 224-231 and read about colloids suspensions and solutions. Define in your notes the italicized words. What is a colloid? What is a suspension? How are they different from a solution?

Classification of Matter Solutions Colloids Suspensions Homogeneous Heterogeneous Particle size: 0.01–1 nm 1–1000 nm over 1000 nm Do not separate on standing Particles settle out, Shake before use. Cannot be separated by filtration or membrane. Cannot be separated by filtration. Only by membrane Can be separated by filtration or membrane. Do not scatter light Scatter light (Tyndall effect) May scatter light, but are not transparent

Classification of Matter List an example of each below: Element  Zinc Compound  Carbon Dioxide Solution  Stained glass Solid Mixture  Granite Suspensions  Pulpy Orange Juice Colloids  Milk, Jell-O, Hair Spray In one minute I will unveil possible answers. For homework come up with two other examples of each of the classifications of matter.
