Chemistry vocabulary words - solution
| 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 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. |
