1. WHAT ARE THESE?

2. An Introduction to Solutions
The Components, The process, & The Types.

3. A solution & its components
A solution is a homogeneous mixture made up of 2 or more substances in a single phase.
The 2 Components: Solute & Solvent

4. Which is the solute? Which is the solvent?
Silver is dissolved in gold.
Oxyclean is added to a grass stain to get rid of it.

5. Exploring Dissolution: THE Sugar Lab
What are the three ways to increase the dissolution of a solute in a solvent?

6. Surface Area & Its Affect on Dissolution
Surface area is the amount of solute particles exposed to solvent particles.
As surface area increases, dissolution speeds up.

7. Agitation & Its Affect on Dissolution
Stirring or shaking helps solute particles disperse and bring fresh solvent into contact with the solute surface.

8. Heat & Its Affect on Dissolution
As temperature of the solvent increases, solvent particles move faster and causes more frequent collisions between the solute and solvent particles.

9. An unsaturated solution can dissolve more solute.
types of Solutions
An unsaturated solution can dissolve more solute.
A saturated solution contains the maximum amount of solute it can dissolve.
A supersaturated solution has more solute than possible dissolved.

10. Which beaker represents a saturated solution? Explain.
types of Solutions
Which beaker represents a saturated solution? Explain.

11. The data provided refers to an experiment in which a measured mass of solid was added to 10.0 g of water at 20⁰C. The mixture was stirred and allowed to sit for 3 hours. Ten separate trials were conducted for the experiment and the following data was collected.

12. What does this data tell you?

13. Would Trial 3 represent Beaker C or D? Explain.

14. The data provided refers to an experiment in which a measured mass of solid was added to 10.0 g of water at 20⁰C.
If this experiment were repeated using water held at 40⁰C, what do you think would change?
