Honors Chem Ch 13/14

QuestionAnswer
Colloid A mixture in which the solute particles are so small that they do not settle out and cannot be filtered out but they can be seen using a beam of light.
Electrolyte A substance that dissolves in water to give a solution that conducts electric current
Non-electrolyte A substance that dissolves in water to give a solution that does not cunduct 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 large enough to settle out unless the mixture is constantly stirred or agitated
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 solutes and solvents 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 specifid temperature
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 existing conditions
Concentration A measure of the amount of solute in a given amount of solvent or solution
Molarity A way of measuring concentration by calculating the number of moles of solute in one liter of solution
Dissociation The separation of ions that occurs when an ionic compound dissolves
Hydronium Ion The H30+ ion
Ionization The energy required to remove one electron from a neutral atom of an element
Net Ionic Equation An equation that includes only those compounds and ions that undergo a chemical change in a reaction in an aqueous solution
Spectator Ions An ion that does not take part in a chemical reaction and is found in solution both before and after the reaction
Strong Electrolyte Any compound of which all or almost all of the dissolved compound exists as ions in aqueous solution
Weak Electrolyte A compound of which a relatively small amount of the dissolved compound exists as ions in an aqueous solution
Boiling-Point Elevation A colligative property that is the difference between the boiling point of a pure solvent and a nonelectrolyte of that solvent, directly proportional to the concentration of the solution
Colligative Properties Properties that depend on the concentration of solute particles but not on their identity
Freezing-Point Depression A colligative property that is the difference between the freezing points of a pure solvent and a solution of a nonelectrolyte in that solvent; is directly proportional to the concentration of the solution
