1. Solubility & Saturated Solutions

2. Solubility Is usually measured in grams per unit volume of solvent.
For example, grams/liter.
The solubility of a solute changes with temperature.
For example:
You can dissolve a lot more sugar in hot tea than in cold tea.
Cold water has a lot more dissolved oxygen than does warm water.

3. Saturated solutions
…are solutions in which the solvent can not hold anymore solute (at a given temperature).

4. Volume and Dissolving
What happens to the volume of a solution when you dissolve a solute into a solvent?
Does it go up, down, stay the same??
(Do lab 14) to find out what happens.

5. Mass and Dissolving
What happens to the mass of a solution when you dissolve a solute into a solvent?
Does it go up, down, stay the same??
(Do lab 14) to find out what happens.
