2. I Electrolytic Cell- a device used to produce a redox reaction by supplying an electric current to an aqueous solution of an electrolyte.
An electrolytic cell has 3 essential parts:
A source of direct current that provides the energy that causes the reaction to occur- a battery or a dry cell.
Two electrodes- an anode(+) and a cathode(-).
An electrolyte- a substance dissolved in water that provides ions, thus balancing the flow of electrons in the external circuit.

3. The process by which an electric current
At the Ag electrode (anode) Ag(s) → Ag+(aq) + e- At the Mg electrode (cathode) Ag+(aq) + e- → Ag(s)
The process by which an electric current
causes a redox reaction in the water
solution of an electrolyte is called
electrolysis.

4. II A. Electroplating- the use of electrolysis to coat a material with a layer of metal. For electroplating to occur, the object to be plated must be a conductor.

5. B. Electrolysis– the production of hydrogen and oxygen from water.

6. III Practical applications of electrolysis
Electroplating
Recovery of active nonmetals (O2, H2, Cl2)
Recharging a battery
