1. A solution is a homogeneous mixture. Which means it has the same composition of elements and/or compounds throughout.

2. SOLUTE – Dissolved material SOLVENT – Dissolving material

3. Many different substances can dissolve in water. For this reason, water is sometimes called the universal solvent.

4. SolidLiquid DISSOLVED IN Examples: Kool-Aid, Lemonade DISSOLVED IN SugarWater

5. Liquid DISSOLVED IN Examples: Vinegar DISSOLVED IN Acetic AcidWater

6. GasLiquid DISSOLVED IN Examples: Soda DISSOLVED IN Carbon Dioxide Water & Syrup

7. Gas DISSOLVED IN Examples: Air DISSOLVED IN Oxygen (~21%), Argon (~1%), Carbon Dioxide & a few other gases Nitrogen (~78%)

8. LiquidSolid DISSOLVED IN Examples: Dental fillings (amalgam) DISSOLVED IN MercurySilver

9. Solid DISSOLVED IN Examples: Alloys, Steel, Brass DISSOLVED IN Carbon Iron (98-nearly 100%)

10. An alloy is a material composed of two or more metals or a metal and non- metal. Alloys are used because their properties are superior to the properties of the pure component elements. Examples include steel, solder, brass, pewter, bronze, and amalgam.

12. How can you tell what type of solution (solid, liquid, or gaseous) you have? SOLUTE + SOLVENT = TYPE OF SOLUTION Solid+Liquid= + = Gas+Liquid= Gas+ = Liquid+Solid= + = =

13. Assignment Complete types of solutions worksheet and read pages 380-385 in the book.
