Oxidation Losing electrons Reduction Gaining electrons The oxidation state of alkali metals +1 The usual oxidation state of oxygen -2 The oxidation state of halogens -1 Electrochemistry The study of the relationship between chemical reactions and electricity Another word for voltaic Galvanic If the standard electrode potential of a cell is greater than 0 The redox reaction is spontaneous Where oxidation occurs The anode Where reduction occurs The cathode Neutralizes any excess charge buildup The salt bridge Measures the voltage of the electrochemical cell A voltmeter Electrolysis The process by which electrical energy is put into a nonspontaneous redox reaction to force it to occur A type of electrolysis in which one metal is deposited on another Electroplating A reducing agent Undergoes oxidation to cause another species to be reduced An oxidizing agent Undergoes reduction to cause another species to be oxidized The sum of the oxidation potential and the reduction potential Electric potential difference for the overall redox reaction The oxidation state of alkaline earth metals +2 The oxidation state of hydrogen +1 or -1
