Standard Cell Potential and the Nernst Equation
Table:
Just remember, the top one is cathode, bottom one is anode
[!example]
SIMILAR PROBLEM ON FINAL
In a galvanic cell, one half-cell consists of a zinc strip dipped into a 1.0 M solution of Zn(NO3)2. In the second half-cell, solid indium adsorbed on graphite is in contact with a 1.0 M solution of In(NO3)3. Indium is observed to plate out as the galvanic cell operates, and the initial cell voltage is measured to be 0.425 V at 25 °C.
Concentration Cell
Cation, higher concentration is the cathode
Anion: higher concentration is the anode (electrons move to element with lower concentration)
EXAMPLE 6.11 IMPORTANT FOR FINAL
If not equilibrium but supply the mass change of nickel and ask cell potential
