Document Summary
Oxidative reduction reactions or redox reactions are reactions in which electrons transfer from one reactant to another. Redox reactions do not need to involve oxygen. Oil rig oxidation is loss reduction is gain. Metal has a tendency to loose electrons reacts with a non metal which has a tendency to gain electrons. In both cases, metal atoms loose electrons to non metal atoms. Oxidation is a loss of electrons and reduction is the gain of electrons. The transfer of electrons needs not to be a complete transfer for the reaction to quality as a complete transfer. 18. 3 voltaic (or galvanic) cells: generating electricity from spontaneous chemical. Electrical current is the flow off electric change. Since redox reactions involve the transfer of electrons they have the potential to generate electrical current. The generation of electrical through redox reaction is normally carried out in a device called a electrochemical cell.
