Voltaic Cells: Redox Reactions
1) The oxidation half-cellñThe electrode conducts electrons out of its
half-cell.
2) The reduction half-cellñThe electrode conducts electrons into its
half-cell.
3) Relative charges on the electrodesñIn any voltaic cell, the anode is
negative and the cathode is positive
4) Purpose of the salt bridgeñAs electrons move left to right through the
wire, anions and cations move in the salt bridge.
