Devan - vocabulary


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 singlephase
Aqueous any solution in which water is disolvent
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 technique of heating a liquid to create vapor which is collected when cooled, separate from the original liquid
Filtering a membrane or layer that is designed to physically block certain objects or substances while letting others through
Chromatography separating mixtures based on differences in the speed at which they migrate over, or through
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 ansd that separates from the solution
Ionic equation and equation that includes only those compounds and ions that undergo a chemical change
Molecular equation balanced chemical equation in which ionic compounds are 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 solution both before and after the reaction
Acid proton donor that yields hydronium ions in water solution, or electron-pair acceptors that combine with electron-pair donors or bases
Base a compound that reacts with an acid to form a salt
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 adding solvent to a solution to lower its concentration
Titration the controlled addition and measurement of the amount of a solution of known concentration measured amount of a solution of unknown concentration
Concentration a measure of the amount of solute in a given amount of solvent or solution
