Introduction:
Solubility is the ability of a solid, liquid, or gaseous chemical substance (referred to as the solute) to dissolve
in solvent (usually a liquid) and form a solution. The solubility of a substance fundamentally depends on the
solvent used, as well as temperature and pressure. The solubility of a substance in a particular solvent is
measured by the concentration of the saturated solution. A solution is considered saturated when adding
additional solute no longer increases the concentration of the solution
Objective:
To identify the type of mixture by visible examination
Estimated Time Frame: 15 minutes
Materials:
. 3 clear glasses, water, sand, and salt
Procedure:
of
1. In each glass, pour the same amount of water.
2. In one glass, add the sand. In the other glass, mix the salt in the water.
3. Leave the third glass with only water in it.
4. Let one of your family member shuffle the three glasses.
Questions
1. By just looking at the contents of the glasses, can you identify which is salt water, pure water, and water with
sand? Explain your answers.
2. Which was easier to identify, the glass with water and sand or the glass with salt water? Why? How about
between the glass with pure water and the glass with salt water?

Answer:
Definition of Solubility
Solubility is the ability of a solid, liquid, or gaseous chemical substance (referred to as the solute) to dissolve in solvent (usually a liquid) and form a solution. The solubility of a substance fundamentally depends on the solvent used, as well as temperature and pressure. The solubility of a substance in a particular solvent is measured by the concentration of the saturated solution. A solution is considered saturated when adding additional solute no longer increases the concentration of the solution.
The degree of solubility ranges widely depending on the substances, from infinitely soluble (fully miscible), such as ethanol in water, to poorly soluble, such as silver chloride in water. The term “insoluble” is often applied to poorly soluble compounds. Under certain conditions, the equilibrium solubility can be exceeded, yielding a supersaturated solution.
Solubility does not depend on particle size; given enough time, even large particles will eventually dissolve.
