Aqueous Solution Vocabulary

Vocabulary WordDefinition
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 dissolved in water
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 contains the maximum amount of dissolved solute
Unsaturated contains less solute that a saturated solution under the existing conditions
Supersaturated contains more dissolved solute than a saturated solution contains under the same conditions
Distillation the purification or concentration of a substance
Filtering removing by using an object that removes impurities or other substances from a certain substance
Chromatography the separation of mixtures into their constituents by preferential adsorption by a solid, as a column of silica or a strip of filter paper
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
Dissociation 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 equations that show only the soluble, strong electrolytes reacting and omit the spectator ions
Molecular equation An equation with all of the elements given including the spectator ions.
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 compound containing hydrogen that can be replaced by a metal or an form a salt, or containing an atom that can accept a pair of electrons from a base.
Base a group or molecule that takes up or accepts protons; a compound that reacts with an acid to form a salt, as ammonia, calcium hydroxide, or certain nitrogen-containing organic compounds.
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 experie electropositive group tonce 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 number of moles of solute per kilogram of solvent
Dilution The act of reducing the concentration of a mixture or solution
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
