Chemistry

QuestionAnswer
Solute The substance dissolved in a solution.
Solvent The dissolving medium in a solution.
Solution A homogeneous mixture of two or more substances in a single phase.
Aqueous A solution in which the solvent is water.
Freezing Point Depression The difference between the freezing points of a pure solvent and a solution of a nonelectrolyte in that solvent.
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 Contains the maximum amount of dissolved solute.
Unsaturated Contains less solute than the satrated solution.
Supersaturated Contains more dissolved solute than a saturated solution contains under the same conditions.
Distillation Method of separating mixtures based on differences in their volatilities in a boiling liquid mixture.
Filtering A membrane or layer that is designed to physically block certain objects or substances while letting others through.
Chromatography Term for a set of laboratory techniques for the separation of mixtures.
Solubility The ability of a substance to dissolve in a solution.
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 uniform composition throughout.
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.
Colloid A mixture consisting of particles that are intermediate in size between those in solutions and suspensions forming mixtures known as colloid dispersions.
Disassociation Partial or complete disruption of the normal integrations of a persons conscious or psychological functioning.
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.
Precipitate A solid that is produced as a result of a chemical reaction in solution and that separates from the solution.
Ionic Equation Chemical equation in which electrolytes are written as dissociated ions.
Molecular Equation Chemical equation written as if all components exist as molecules.
Spectator Ion An ion that does not take part in a chemical reaction and is found in solution both before and after the reaction.
Acid Compounds that contain hydrogen and can dissolve in water to release hydrogen ions into solution.
Base Substances that dissolve in water to release hydroxide into solution.
Neutralization The reaction of hydronium ions and hydroxide ions to form water molecules.
Oxidation A reaction in which the 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 solute.
Dilution Reduction of concentration of an active substance by admixture of a neutral agent.
Titration The controlled addition and measurement of the amount of a solution of known concentration measured amount of a solution of unknown concentrations.
Concentration A measure of the amount of solute in a given amount of solvent or solution.
