Ch. 12 + 13 Solubility and Solution Properties

Vocabulary flashcards based on the Chapter 12 and 13 study guide covering solubility, electrolytes, colloids, and saturation.

Pure solvent

A substance containing only one type of molecule, such as $H_2O$, carbohydrates, benzene, or chloroform.

Boiling point elevation

The phenomenon where the boiling point of a solution is higher than that of the pure solvent.

Freezing point depression

The phenomenon where the freezing point of a solution is lower than that of the pure solvent.

Electrolytes

Substances that break up into ions when dissolved and conduct electricity.

Nonelectrolytes

Substances that do not form ions in solution or conduct electricity.

Colloids

Mixtures containing particles that are larger than solution particles (size in-between solutions and suspensions) and scatter light.

Tyndall effect

A light scattering effect that makes a beam of light visible, such as headlights in fog.

Unsaturated

A state where the amount of solute dissolved is less than the maximum at a given temperature.

Saturated

A state where the solution holds the maximum amount of solute at a given temperature.

Supersaturated

An unstable state where a solution contains more than the maximum amount of solute at a given temperature; example includes rock candy.
