1. Solutions and Solubility

2. Review from last class…
What is a solute?
What is a solvent?
What does soluble mean?
For the following examples decide which is the solute and which is the solvent:
Water and kool-aid powder
Water and baking soda
Food coloring and water
Sulphur dioxide (gas) and rain- Acid Rain

3. Solutions Worksheet Finish the worksheet as partners (10 minutes)
Correct as a class

4. How can you tell if you have a liquid solution?

5. How can you tell if you have a liquid solution?
Write a summary in your notes in your own words
The solvent is a liquid. The solute and solvent are evenly mixed. You cannot see the solute and solvent separately (appear as one). The mixture is transparent (you can see through it).

6. Review: Solutes and Solvents
Solutions are often liquid based
A liquid solution always has at least one liquid
The solute in a liquid solution can be any state of matter
In the solution of liquids and solids or of liquids and gases, the solvent is ALWAYS the liquid

7. Solutes and Solvents Cont’d
REVISION**In solutions of liquid & liquid, we usually DO NOT name the solute and solvent**
We can determine the solute and solvent of a liquid/liquid; solid/solid; gas/gas solution based on how much of each pure substance there is in the mixture
The one with greater quantity is considered the solvent
The substance which there is a lesser quantity is the solute

8. Solutions from A to Z Put name on worksheet
