Solubility

1
Solubility

• The ability of a substance to be dissolved in a
  solvent

2
Making solutions

• Unsaturated a solution that can have more solute
  dissolved in it at a given temperature.
• Saturated a solution that can no longer dissolve
  anymore solute at a given temperature.
• Supersaturated a solution that contains more
  solute dissolved at a given temperature than can
  normally be dissolved a single piece of the
  solute or agitation is enough to make the
  solution solidify

How does heat affect solubility?

• Think about a glass of iced tea.
• How can you make your iced tea have more sugar in
  it?
• What can you do?
• Is this solubility? Why?

Solubility in Chemistry

• Solubility can be described by a graph
• Compares number of grams of solute in100 grams of
  water to temperature, C.
• Each line represents the maximum amount of that
  solute that can be dissolved at different
  temperatures.
• Therefore each line can be considered a
  saturation line.

5
Reading the graph

• Look for the solute your are using, and use the
  axis to predict either the temperature or the
  amount for a saturated solution.
• Ex What amount of KNO3 is needed to make a
  saturated solution at 50 C?
