| A | B |
|---|
| oxidation | loss of electrons; becomes more positive |
| reduction | gain of electron; becomes more negative |
| redox | a reaction in which both reduction and oxidation occur |
| oxidation number (states) | identify how many electrons will be lost or gained by an atom or ion |
| oxidizing agent | the substance that will be reduced |
| reducing agent | the substance that will be oxidized |
| half-reaction | an equation showing either the oxidation or reduction portion of a redox reaction |
| salt bridge | a passageway for the movement of ions in an electrochemical cell |
| electrode | the site at which oxidation or reduction occurs; anode or cathode |
| anode | an electrode; the site of oxidation in an electrochemical cell |
| cathode | an electrode; the site of reduction in an electrochemical cell |
| voltmeter | used to detect the a electrical potential; electron flow |
| electrochemical cell | a cell in which the redox reaction is conducted in such a way that the electrons travel therough a wire between the substance being oxidized and the substance being reduced |
| electrolytic cell | a cell that requires electricity to cause a nonspontaneous chemical reaction to occur |
| electroplating | the process of layering a metal onto a surface in an electrolytic cell |
| electrolysis | a chemical reaction that takes place when an electric current is applied to a substance |
