Unit 9 solubility curves

​•Shows the maximum

•number of grams that

•can be dissolved in 100g

•of H2O at specific

•temperatures

•Most show increasing solubility as temperature increases, but a few don’t

–These are gaseous NH3, HCl, SO2

–Gases decrease in solubility as temperature increases

•Where the curves intersect, shows where those solutions are equally soluble

ANY SOLUTION CAN BE MADE SATURATED, UNSATURATED, OR SUPERSATURATED BY CHANGING THE TEMPERATURE.

SOLUBILITY CURVE

Points B and C

•Points of saturation (anywhere on the line)

•Saturated solutions

​

Points A and E

•Supersaturated solutions

​

Point D

•Unsaturated solutions

Temperature (°C)​
