Galvanic cell

Converts chemical energy to electrical energy

Three essential galvanic cell components

Electrodes, electrolyte solutions, salt bridge

Half cell

Electrode representing half of complete redox reaction

Electrolyte

Substance conducting electricity when dissolved/melted

Salt bridge function

Maintains electrical neutrality in electrode solutions

Anode

Electrode where oxidation occurs (negative terminal)

Cathode

Electrode where reduction occurs (positive terminal)

Negative terminal reaction

Oxidation (electrons released)

Positive terminal reaction

Reduction (electrons absorbed)

Common salt bridge electrolyte
