UNIT 6 SOLUTIONS AND GASES 6.1 What is a solution? April 7, 2011 AIM: How do we define solution? DO NOW: 1. What is the difference between a heterogeneous mixture and a homogeneous mixture? 2. Give one example of a homogeneous mixture. 3. Give one example of a heterogeneous mixture. HETEROGENEOUS  particles are NOT uniformly spread out HOMOGENEOUS  particles ARE uniformly spread out KOOLAID and WATER OIL and WATER SOIL

What is a solution? A solution is a ________________ mixture of substances. There are 2 parts of a solution: _____________________ HOMOGENEOUS SOLUTE SOLVENT

SoluteSolvent Substance BEING DISSOLVED Present in SMALLER AMOUNT Substance that DISSOLVES Present in LARGER AMOUNT
