| Question | Answer |
|---|---|
| Anode | SPONTANEOURSLY LOSES ELECTRONS to cathode; the NEGATIVE electrode in a VOLTAIC CELL; electrode where OXIDATION occurs; The MORE ACTIVE of the 2 metals goes here. |
| Cathode | SPONTANEOUSLY ATTRACTS ELECTRONS to it; the POSITIVE electrode in a VOLTAIC CELL; electrode where REDUCTION occurs; The LESS ACTIVE of the 2 metals goes here. |
| Electrochemical Cell | Involve redox reactions and the flow of electrical energy |
| Electrode | (conductive surfaces where oxidation or reduction occurs) |
| Electrolytic Cell | Cells that use ELECTRICAL ENERGY to force a NONSPONTANEOUS CHEMICAL REACTION to occur |
| Galvanic or Voltaic Cell | Cells that SPONTANEOUSLY convert CHEMICAL energy into ELECTRICAL energy or electric CURRENT; BATTERIES |
| Half reaction | Allow us to show the EXCHANGE OF ELECTRONS in a redox rxn; 1 for oxidation and 1 for reduction |
| Oxidation Half Reaction | Loss OF ELECTRONS by an atom or ion |
| Oxidation Number | POSITIVE, NEGATIVE, OR NEUTRAL (ZERO) VALUES that can be assigned to atoms; used to identify how many electrons are being lost or gained by an atom/ion when they FORM BONDS |
| Oxidizing agent | SPECIES that is REDUCED; species that DOES THE OXIDIZING |
| Redox | Reactions that involce the TRANSFER OF ELECTRONS |
| Reducing Agent | SPECIES that is OXIDIZED; species that DOES THE REDUCING |
| Reduction Half Reaction | GAIN OF ELECTRONS by an atom or ion |
| Salt Bridge | Provides a path for the FLOW OF IONS between the half-cells |
