Science Chapter 9 Terms

Suspension

Heterogeneous mixture of a fluid and large particles that will eventually settle out.

Colloid

Heterogeneous mixture in which the particles are too small to settle and thus remain dispersed.

Solution

Homogeneous mixture where the solute is uniformly distributed within the solvent.

Solute

The material that dissolves in a solution.

Solvent

Substance into which a solute dissolves.

Alloy

Solid solution made of two or more elements, at least one of which is a metal.

Dissociation

Breaking apart of the ions in a solid ionic compound by the action of the solvent.

Solubility

The maximum amount of solute that can dissolve in a given amount of solvent at a certain temperature.

Concentration

The actual amount of solute dissolved in a given amount of solution.

Saturated Solution

Contains the maximum amount of solute that the solution can hold at a temperature.

Unsaturated Solution

Solution that contains less than the maximum amount of solute that it could hold at that temperature.

Supersaturated Solution

Solution that contains more than the maximum amount of solute that it can normally hold at that temperature.

Molarity

Number of moles of solute per liter of solution.

Colligative Properties

Properties that change from its parent solvent due to adding solute.
