QuestionAnswer
Solute a substance dissolved in water.
Solvent is a liquid, solid, or gas that dissolves another solid, liquid, or gaseous solute.
Aqueous a solution in which the solent is water.
Freezing Point depression the difference between the freezing points of a pure solvent and a solution of a non electrolyte in that solvent; is directly proportional to the molar concentration of the solution.
Boiling Point elevation the difference between the boiling point of a pure solvent and a nonelectrolyte of that solvent, directly proportional to the molal concentration of the solution.
Saturated a solution that contains the maximum amount of dissolved solution.
Unsaturated a solution that contains less solute than a saturated solution under the existing conditions.
Supersaturated a solution that contains more dissolved solute than a saturated solution contains under the same conditions.
Distillation a method of sperating mixtures based on the differences in the volatilities in a boiling liquid mixture.
Filtering seperating particles from a liquid through a porous material.
Chromatography the labratory term for separating mixtures.
Solubility the amount of a substance required to form a saturated solution with a specific amount of solvent at a specific temperature.
Mixture a blend of two or more kinds of matter, each of which retains its own identity and properties.
Homogeneous having a uniform composition throughout.
Heterogeneous not having a composition reaction throughout.
Suspension a mixture in which the particles in which the particles in the solvent are so large that they settle out unless the mixture is constantly stirred or agitated.
Colloid a mixture consisting of particles that are intermediate in size between those in solutions and suspensions forming mixtures known as colloid dispersions.
Dissociation the separation of ions that occurs when an ionic compound dissolves.
Electrolyte a substance that dissolves in water to 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.
Precipitate a solid that is produced as a result of a chemical reaction and that separates from the solution.
Ionic equation symbolic representation of a chemical equation where the reactant entities are given on the left hand side and the product entities on the right.
Molecular equation balanced equation in which ionic compound re written as neutral formulas rather than as ions.
Spectator ion an ion that does not take part in a chemical reaction and is found in a solution both before and after the reaction.
Acid a substance that reacts with a base.
Base the ability to react with acids to form salts.
Neutralization the reaction of hydronium ions and and hydroxide ions to form water molecules.
Oxidation a reaction in which the ions or atoms of an element experience an increase in oxidation state.
Reduction a reaction in which the oxidation state of an element decreases.
Molarity the number of moles of solute in one liter of solution.
Molality the concentration of a solution expressed in moles of solute per kilogram of solvent.
Dilution the process of making weaker or less concentrated.
Titration the controlled addition and measurement of the amount of a solutionof known concentration required to react completely with a measured amount of a solution of unknown concentration.
Concentration a measure of the amount of solute in a given amount of solvent or solution.
