| 601. | Valence Shell Electron Pair Repulsion Theory | Assumes that electron pairs are arranged around the central element of a molecule or polyatomic ion so that there is maximum separation (and minimum repulsion) among regions of high electron More… |
| 602. | van der Waals' Equation | An equation of state that extends the ideal gas law to real gases by inclusion of two empirically determined parameters, which are different for different gases. |
| 603. | Vapor | A gas formed by boiling or evaporating a liquid. |
| 604. | Vapor Pressure | The particle pressure of a vapor at the surface of its parent liquid. |
| 605. | Voltage | Potential difference between two electrodes; a measure of the chemical potential for a redox reaction to occur. |
| 606. | Voltaic Cells | Electrochemical cells in which spontaneous chemical reactions produce electricity; also called galvanic cells. |
| 607. | Water Equivalent | The amount of water that would absorb the same amount of heat as the calorimeter per degree temperature increase. |
| 608. | Weak Electrolyte | A substance that conducts electricity poorly in a dilute aqueous solution. |
| 609. | Weak Field Ligand | A Ligand that exerts a weak crystal or ligand field and ge- nerally forms high spin complexes with metals. |
| 610. | Zone Refining | A method of purifying a bar of metal by passing it through an induction heater; this causes impurties to move along a melted portion. |
