Term
Colloid
Definition
A mixture consisting of particles that are intermediate in size between those in solutions and suspensions forming miztures known as colloid dispersions.
Term
Electrolyte
Definition
A substance that dissolves in water to give a solution that conducts electric current.
Term
Nonelectrolyte
Definition
A substance that dissolves in water to give a solution that does not conduct an electric current.
Term
Soluble
Definition
Capable of being dissolved.
Term
Solute
Definition
The substance dissolved in a solution.
Term
Solution
Definition
A homogeneous mixture of two or more substances in a single phase.
Term
Solvent
Definition
The dissolving medium in a solution.
Term
Suspension
Definition
A mixture in which the particles in the solvent are so large that they settle out unless the mixture is constantly stirred or agitated.
Term
Effervescence
Definition
The rapid escape of a gas from the liquid in which it is dissolved.
Term
Heat of Solution
Definition
The net amount of energy absorbed as heat during a chemical reaction.
Term
Henry's Law
Definition
The solubility of a gas in a liquid is directly proportional to the partial pressure of that gas on the surface of the liquid.
Term
Hydration
Definition
A solution process with water as the solvent.
Term
Immiscible
Definition
Liquid solutes and solvents that are not soluble in each other.
Term
Miscible
Definition
Liquid solvents and solutes that are able to dissolve freely in one another in any proportion.
Term
Saturated Solution
Definition
A solution that contains the maximum amount of dissolved solute.
Term
Solubility
Definition
The amount of a substance required to form a saturated solution with a specific amount of solvent at a specified temperature.
Term
Solvated
Definition
A solute particle that is surrounded by solvent molecules.
Term
Solution Equilibrium
Definition
The physical state in which the opposing processes of dissolution and crystallization of a solute occur at equal rates.
Term
Supersaturated Solution
Definition
A solution that contains more dissolved solute than a saturated solution contains under the same conditions.
Term
Unsaturated Solution
Definition
A solution that contains less solute than a saturated solution under the exsisting conditions.
Term
Concentration
Definition
A measure of the amount of solute in a given amount of solvent or solution.
Term
Molality
Definition
The concentration of a solution expressed in moles of solute per kilogram of solvent.
Term
Molarity
Definition
The number of moles of solute in one liter of solution.
