Final Flashcards
Galvanic Cell
Battery that works (not dead)
Where do electrons flow in a galvanic cell?
From the oxidation half-cell to the reduction half-cell (anode to cathode)
Where does oxidation occur in a galvanic cell?
At the anode
Where does reduction occur in a galvanic cell?
At the cathode
What does a salt bridge do?
Maintains charge-neutrality in each half-cell, allowing electrical current to flow from the anode to cathode
Electromotive force (emf)
Force on the electrons that causes them to flow
positive cell potential
spontaneous
negative cell potential
nonspontaneous
S.H.E.
1/2 cell potential of the Standard Hydrogen Electrode = 0 V
Standard Reduction Potentials
The 1/2 cell potentials that are determined by refrence to SHE
More positive E°
More spontaneous
Negative E°
Nonspontaneous
