Notes on lesson on Solubility | kullabs.com

#### Solubility

After completion of this lesson, student must be able to:

• Define solution and its types.
• Prepare different types of solution.
• Define solubility of a substance.
• Define the relation between solubility of a substance and temperature.
• Obtain crystals from a saturated solution.

#### Mixture

A mixture is defined as a mass obtained by mixing up two or more chemically non-reactive substances in any proportion by weight. A homogeneous mixture is defined as a mass in which the particles of the components of the mixture are equally distributed. A heterogeneous mixture is defined as a mass in which the particles of components of the mixture are not equally distributed. This note gives further information about solubility, mixture, solution, colloids and suspensions.

#### Solubility of Substance and Crystallization

The solubility of a substance (solute) at a given temperature is defined as the amount of substance (solute) dissolved in 100 gm. of solvent to make a saturated solution at that temperature. This note provides us the information about solubility of substance, solubility curve and crystallization

#### Solution

The solution that has relatively a less amount of solute for a given amount of solvent is called dilute solution. The solution that has relatively a large amount of solute for a given amount of solvent is called concentrated solution. The solution, which can dissolve excess solute at the given temperature, is called unsaturated solution at that temperature. This note gives us the information about different types of solution.
