Unformatted text preview: Objectives for Electrochemistry Lecture • A common language understanding of Galvanic and Electrolytic Cells • A common language understanding of the relationship between Gibbs Free Energy and Electrical work • Using Standard Cell voltages (Standard Reduction Potentials) • Using Half Cell Voltages to evaluate cell reactions and potentials Electrochemical Cells • Galvanic cells generally convert chemical energy for spontaneous reactions into electrical energy • Electrolytic cells generally convert electrical energy into chemical energy by creating species with higher free energy • Copper/silver Galvanic Cell • Trace circuit through loop • In metal electron can move in solution ions can move • Salt bridge allows charges to move but minimizes mixing of ions in cell compartments Electrochemical Cell • Cu(s) → Cu 2+ (aq) + 2e- “LEO” -anode-left • Ag + (aq) + e- → Ag(s) “GER” - Cathode • In external circuit - electron flow from anode to cathode • In solution, anions move toward anode, cations move toward the cathode....
