Name one solution we experimented with in our lab?
Saltwater

What process do you use to saturate a solution?
1. Take 50 ml of water and pour it into a bottle.
2. Take a funnel and pour 5 ml of a solute into the bottle.
3. Shake thoroughly
4. Check for saturation
5. Repeat

What two solutes did we use in our saturation labs?
Salt and Citric Acid
300
A solvent is...
Liquid that dissolves the solute (solid).

What does saturation look like in a bottle?
Solute has covered the bottom of the bottle and can no longer dissolve into the solvent.
400
A saturated solution is...
When a solvent (liquid) has dissolved as much material as it can.

What is solubility?
The maximum amount of a solute that can dissolve in a solvent is called the _________________.
