1. Saturated and Unsaturated Solutions

2. Dissolving How does something dissolve to make a solution?
Dissolving Animation
Activity: Measure out 20mL of water and 5 g of sugar. Dissolve. Add 5 more grams and continue until saturated. Keep track of the total amount of sugar to calculate the final concentration in g/L.

3. How much can be dissolved?
Do you think there is a limit to how much can be dissolved in a solvent?
Can you make it more and more concentrated?

4. Unsaturated Solution
More solute could dissolve at the same temperature.
More solvent particles are available to dissolve solute.

5. No more solute will dissolve at a specific temperature.
All of the solvent particles are already attracted to as many solute particles as they can be.
Saturated Solution

6. SuperSaturated Solution
Has been heated to dissolve the maximum amount of solute and cooled without stirring.
When a single crystal is added to the solution, it grows until the whole solution becomes a solid.
SuperSaturated Solution

7. Saturated and Unsaturated Solutions
Fill-in the blanks using the following terms:

In this lab the ___________ is the ____________, and the_____________ is the __________.
The first solution is more ____________, than the second solution.
The third solution is more ______________ than the second solution.
The second solution can be described as having a ________________ of ________g/L.
When we can't add any more sugar, we say that the solution is __________________.
