Redox Reaction

4. Number assigned to keep track of electron gain or loss in redox reactions.
6. A process in which an electric current forces a nonspontaneous reaction to occur.
8. Electrochemical cell in which a spontaneous chemical reaction causes a flow of electrons
11. Is the slow addition of one solution of a known concentration (called a titrant) to a known volume of another solution of unknown concentration until the reaction reaches neutralization, which is often indicated by a color change.
13. Reaction that shows either the oxidation or reduction portion of a redox reaction.
14. The negatively charged electrode of an electrical device.
15. A cell that requires a nonspontaneous chemical reaction to occur (uses battery).

1. A substance that tends to bring about reduction by being oxidized and losing electrons.
2. Site at which oxidation or reduction; an anode or cathode.
3. A system in which there's an electric current flowing while a chemical reaction occurs.
4. The loss of electron.
5. An oxidation-reduction reaction.
7. The gain of electron.
9. Part of a voltaic cell that connects two containers and allows flow of ions.
10. A substance that tends to bring about oxidation by being reduced and gaining electrons.
12. The positively charged electrode of an electrical device.
