| dissociation | the breaking apart of an ionic compound (such as salt) into positive and negative ions when dissolved in water |
| electrolyte | a substance that separates or forms ions in a water solution, making the solution an electrical conductor |
| ionization | the breaking apart of certain polar substances to form ions when dissolved in water |
| nonelectrolyte | a substance, such as pure water, that does not conduct electricity |
| organic solvent | a type of liquid often found in building materials; contains potentially harmful chemicals |
| saturated solution | a solution that has dissolved all the solute it can normally hold at a specific temperature |
| solubility | the amount of a substance (solute) that will dissolve in a solvent; generally expressed as the maximum number of grams of solute that will dissolve in 100 g of a solvent at a specific temperature |
| solute | the substance being dissolved in a solvent |
| solvent | the substance that dissolves in a solute |
| supersaturated solution | an unstable solution that contains more solute than a saturated solution can at that same specific temperature |
| unsaturated solution | a solution that is capable of dissolving more solute at a specific temperature |
