Solution Vocabulary

Chemistry vocabulary words - solution

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 or mixture in which water is the solvent.
Freezing Point depression the difference between the freezing points of a pure solvent and a solution of a nonelectrolyte in that solvent; is directly proportional to the molal 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 solute.
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 the technique of heating a liquid to create vapor which is collected when cooled separate from the original liquid.
Filtering a device (usually a membrane or layer) that is designed to physically block certain objects or substances while letting others through.
Chromatography the collective term for a set of laboratory techniques for the separation of mixtures.
Solubility the amount of a substance required to form a saturated solution with a specific amount of solvent at a specified 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 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 the separation of ions that occurs when an ionic compound dissolves.
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 a compound composed of positive and negative ions that are combined so that the numbers of positive and negative charges are equal.
Molecular equation a chemical compound whose simplest units are 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 a chemical species that donates protons or hydrogen ions and/or accepts electrons.
Base a chemical species that donates electrons or hydroxide ions or that accepts protons.
Neutralization the reaction of hydronium ions and hydroxide ions to form water molecules.
Oxidation a reaction in which the atoms or ions 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 reducing the concentration of a solution by adding solvent.
Titration the controlled addition and measurement of the amount of a solution of 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.
