What are solutions? Mr. Heffner

1/5/10

What is a mixture?   A mixture is…

  when 2 (or more) substances are combined

  There are two types of mixtures: “things”

Homogenous   homo = same   Evenly mixed

  Examples:   Salt water   Kool-Aid

Heterogeneous   hetero = different   Not evenly mixed

  Examples:   Sand and water   Oil and water

What is a solution?   A solution is…

  a homogeneous mixture of 2 (or more) substances.   made up of a solute and a solvent

  Solutes are the things that are dissolved   Usually a solid

  Solvents are the things that solutes are dissolved in   Always a liquid   Always larger in quantity

What is a solution?   To make a kool-aid solution,

+ =

solute solvent solution

Examples   Is it a solution?

1.  sugar and water 2.  dirt and water

3.  vegetable soup (vegetables & chicken broth)

  For the following solutions, name the solute and the solvent: 1.  Salt water (salt & water)

  Solute = salt

  Solvent = water

2.  Soda (syrup, CO2, & water)   Solute = syrup, CO2

  Solvent = water

Foldable   Make a foldable and define the following terms:

  Substance   Heterogeneous mixture

  Homogeneous mixture   Solution   Solvent

  Solute   Solid

  Liquid
