| anode | the electrode on whose surface oxidation takes place; anions migrate toward the anode, and electrons leave the system from the anode |
| cathode | the electrode on whose surface reduction takes place |
| electrochemistry | the branch of chemistry that is the study of the relationship between electric forces and chemical reactions |
| electrode | a conductor used to establish electrical contact with a nonmetallic part of a circuit, such as an electrolyte |
| electrode potential | the difference in potential between an electrode and its solution |
| electrolytic cell | an electrochemical device in which electrolysis takes place when an electric current is in the device |
| electroplating | the electrolytic process of plating or coating an object with a metal |
| half-cell | a single electrode immersed in a solution of its ions |
| reduction potential | the decrease in voltage that takes place when a positive ion becomes less positive or neutral or when a neutral atom becomes negative ion |
| voltaic cell | a primary cell that consists of two electrodes made of different metals immersed in an electrolyte; used to generate voltage |
