Solutions Key Terms Flashcard

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