| Question | Answer |
|---|---|
| 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 point 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 non-electrolyte of that solvent, directly proportional to the molar 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 | is a method of separating mixtures based on differences in there velocities in a boiling liquid mixture. |
| Filtering | a device (usually a membrane or layer) that is designed to physically block certain objects or substances while letting others through. |
| Chromatography | is the collective term for a set of laboratory techniques for the separation of mixtures. |
| Solubility | is the property of a solid, liquid, or gaseous chemical substance called solute to dissolve in a liquid solvent to form a homogeneous solution of the solute in the solvent. |
| Mixture | is a material system made up by two or more different substances which are mixed together but are not combined chemically. |
| Homogeneous | A substance that is uniform in composition. |
| Heterogeneous | two or more substances which have been combined such that each substance retains its own chemical identity. |
| Suspension | is a heterogeneous fluid containing solid particles that are sufficiently large for sedimentation. |
| Colloid | a substance microscopically dispersed evenly throughout another substance. |
| Disassociation | a partial or complete disruption of the normal integration of a person’s conscious or psychological functioning. |
| Electrolyte | is any substance containing free ions that make the substance electrically conductive. |
| Non-electrolyte | A substance that does exist in an ionic form in aqueous solution. |
| Precipitate | is the formation of a solid in a solution or inside another solid during a chemical reaction or by diffusion in a solid. |
| Ionic equation | is a chemical equation for a reaction which lists only those species participating in the reaction. |
| Molecular equation | a balanced chemical equation in which ionic compounds are written as neutral. |
| Spectator ion | is an ion that exists as a reactant and a product in a chemical equation. |
| Acid | is a substance which reacts with a base. |
| Base | a substance that can accept hydrogen ions or more generally, donate electron pairs. |
| 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 | the process of making weaker or less concentrated. |
| 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. |
