Solubility Curve

Temperature changes the solubility of different compounds into a liquid. This change in solubility can be graphed in a solubility curve. Most graphs are nonlinear, and are concave up. Gasses have a negative slope, and solids have a positive slope.

Creative Applications

1. What does the solubility curve tell us about a compound?

2. Find the solubility curve of Sodium Nitrate. What is the solubility (in g/100 cubic cm of water) at 35 degrees? 75 degrees?

3. What does Sodium Nitrates increasing slope tell us about its phase?
