| voltaic cell | spontaneous redox reactions to convert chemical energy into electrical energy |
| reduction potential | this tendency for the half-reaction of either copper or zinc to occur as a reduction half-reaction in an electrochemical cell can be quantified |
| electrode potential | the difference in potential between an electrode and its solution |
| standard electrode potential | the potential of a half-cell under standard conditions measured relative to the standard hydrogen electrode |
| electrolytic cell | if electrical energy is required to produce a redox reaction and bring about a chemical change in an electrochemical cell |
| electroplating | an electrolytic process in which a metal ion is reduced and a solid metal is deposited on a surface |
| electrolysis | process of passing a current through a cell for which the cell potential is negative and causing an redox reaction to occur |
