1. In a galvanic cell, the electrode that acts as a source of electrons to the solution is called the ___________; chemical change that occurs at this electrode is called_________.
Cathode, oxidation
Anode, reduction
Anode, oxidation
Cathode, reduction

2. Line Notation Solid│Aqueous││Aqueous │solid
Anode on the left ││Cathode on the right
Single line different phases
Double line porous disk or salt bridge
If all the substances on one side are aqueous, a platinum electrode is indicated

3. For this reaction:
Cu(s) + Fe+3(aq) → Cu+2(aq) + Fe+2(aq)

4. Under standard conditions, which of the following is the net reaction that occurs in the cell?
Cd│Cd2+││Cu2+│Cu
a. Cu2+ + Cd→ Cu + Cd2+
b. Cu + Cd → Cu2+ + Cd2+
c. Cu2+ + Cd 2+→ Cu + Cd
d. Cu + Cd 2+ → Cd + Cu2+

5. Galvanic Cell
The reaction always runs spontaneously in the direction that produced a positive cell potential.
Four things for a complete description
1)Cell Potential
2)Direction of flow
3)Designation of anode and cathode
4)Nature of all the components-electrodes and ions

6. Practice
Completely describe the galvanic cell based on the following half-reactions under standard conditions.
MnO4-+ 8H++ Se- →Mn2+ + 4H2O E0=1.51V
Fe2++ 3e- → Fe(s) E0=.036V

7. Potential, Work and ΔG
emf= potential
