The key factors that affect solubility include the type of solvent and solute being used, whether the mixture is being stirred or agitated, the size of particles of the solute, and the temperature of the solvent. Solubility refers to whether and how well a solute can dissolve in a solvent.

1. Factors Affecting
Solubility

2. Factors Affecting Solubility
Soluble: When the solute can dissolve in the solvent
Insoluble: When the solute CANNOT dissolve in the solvent

3. Factors Affecting Solubility
1. The type of solvent
Think about our lab and water vs oil. Certain solvents affect how
well something can dissolve.
Water is the most common solvent and is referred to as the
universal solvent

4. Factors Affecting Solubility
2. The type of solute
Think about our lab and sugar, salt or petroleum jelly. The substance
being dissolved affects how well it mixes in.

5. Factors Affecting Solubility
3. Stirring/Agitating the Mixture
Think about our lab stirring vs not stirring water and salt. Stirring
(or other agitations like shaking) will cause the solute to dissolve
into a solvent faster.

6. Factors Affecting Solubility
4. Size of particles
Think about our lab with the loose
sugar vs sugar cubes. All the
particles in the loose sugar are
touching the water vs in the cube
the ones in the center are not
touched by water until the outside
dissolves. Breaking solutes into
smaller pieces allows them to
dissolve faster.

5. Temperature
Think about our lab with
the sugar and different
temperature water. The
warmer the water the
more solute can dissolve in
the solvent.
