Oxidation at the Anode

Reduction at the Cathode

\
S.H.E. is standard hydrogen electrode (2H+ + 2e- → H2)

\
Gibbs free energy = - n * F * E Cell

• n = moles of e-
• F = 96485C / mole e-
• E Cell = cell potential

\

Electrons always flow anode to cathode.

\
Charge = A*S

• A = Current
• S = Time in seconds

\
The Electrolysis of water

2H2O → 2H2 + O2

H+ goes to cathode to be reduced

Cathode: 2H+ + 2e- → H2

Anode: 2O2 → 2e- + O2

H2SO4 is added as a catalyst
