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 |

solute | the substance being dissolved in a solvent |
solvent | the substance that dissolves in a solute |
