Transcript of Solubility
Could something dissolved in the Snake River have caused the fish kill?
These attractions make it possible for water to dissolve lots of different things.
Polar molecules attracted to other polar molecules or ionic compounds

Nonpolar dissolves in nonpolarPolar dissolves in polar
Rule: “Like dissolves Like”
Nonpolar compounds
Why does sugar dissolve in water but not in cooking oil?
Solubility of Solids
Will more sugar dissolve in 1 Liter of water or 2 Liters of water?
Will more sugar dissolve in cold water or hot water?
Solubility curveShows how much solute
will dissolve in a given amount of water at a certain temp.
How much

How much
potassium nitrate
will dissolve at 60
degrees Celsius in
200ml of water?
At what temperature can you dissolve 220g of potassium iodide in 100ml of water?
As temperature increases, what happens to the solubility of solids?
As temperature increases, solubility of solids increases.
Solubility of gases
How much Oxygen will dissolve at 40 degrees Celsius in 100 ml of water?
At what temperature can you dissolve 1.0 mM of Carbon Monoxide in water?
Solubility of gases
As temperature increases, the solubility of gases decreases
