Redox #2

Electrons flow

• through the wire, from the Anode to the Cathode

• through the air, from the Cathode to the Anode

• through the wire, from the Cathode to the Anode

• through a vacuum, from the Anode to the ground

Voltaic Cell

• A device that stores chemical energy

• A spontaneous chemical reaction that produces electricity

• A type of battery that requires external power

• A method for converting electrical energy into chemical energy

Battery

• A device that stores energy for later use

• An outside power source used in an electrolytic cell to force the nonspontaneous redox reaction to occur

• A type of renewable energy source

• A component that converts chemical energy into electrical energy

Cathode

• Reduction occurs at the cathode

• Oxidation occurs at the cathode

• The cathode decreases in mass during the reaction

• Electrons are lost at the cathode

Salt Bridge

• A device that connects two half cells together to allow ions to move from one half cell to the other

• A type of bridge used in construction

• A method for preserving food

• A chemical compound used in cooking

An Ox

Red Fat Cat

• Anode Oxidation

• Oxidation Cathode

• Reduction Anode

• Fat Cat Reduction

Anode

• Reduction occurs at the anode

• Oxidation occurs at the anode

• The anode increases in mass as the metal gains electrons

• The anode is always positively charged

Electrolytic Cell

Electrolysis

Electroplating

• an electric current from an outside power source forces a nonspontaneous redox reaction

• Converts electrical energy to chemical energy

• A spontaneous redox reaction occurs without external energy

• A process that only involves physical changes without chemical reactions
