| desiccants | hygroscopic substances used as drying agents |
| hydrogen bonding | a relatively strong intermolecular force responsible for water's high surface tension |
| suspension | a mixture from which particles settle out upon standing |
| aqueous solution | a solution in which the solvent is water |
| solvent | the dissolving medium in a solution |
| surfactant | wetting agent that interferes with hydrogen bonding in water |
| strong electrolyte | a substance that completely dissociates into its ions in solution |
| water of hydration | the water loosely held in a crystal structure |
| Brownian motion | the chaotic movement of particles in a solution |
| colloid | heterogeneous mixture containing particles that are small enough to remain dispersed in the solvent and do not separate on standing |
| electrolyte | a compound that conducts an electric current when in an aqueous solution or in the molten state |
| emulsion | colloidal dispersion of a liquid in another liquid |
| hydrate | a compound or crystal that contains water of hydration |
| nonelectrolyte | compound that does not conduct an electric current in either an aqueous solution or molten state |
| solute | the dissolved particles in a solution |
| solvation | process by which the positive and negative ions of an ionic solid become surrounded by solvent molecules |
| surface tension | the inward force or pull that minimizes the surface area of a liquid |
| Tyndall effect | scattering of visible light by colloidal particles in a solvent |
| weak electrolyte | substance that conducts electricity poorly because only a fraction of the solute exists as ions in the solvent |
| deliquescent compounds | hygroscopic substances that absorb water from tha air and dissolve completely to form solutions |
