|
Anodic Reaction |
|
|
|
Ti
 Ti3+ +
3
e- |
|
| This is the oxidation reaction. |
|
Titanium will corrode to populate the electrolyte with Titanium ions.
|

 |
e-
electrons conducted
through metal substrate |

|
Cathodic Reaction |
|
|
|
|
2 H2O +
2 e-
H2 + 2 OH- |
|
| This is the reduction reaction. |
|
Dissolved Water will be consumed from the electrolyte, releasing Hydrogen (gas), Hydroxyl molecules/ions back to the electrolyte.
|
|
|
|
|
|
|
|
|
|
|
The driving potential between the two reactions is 0.54 Volts provided the dissolved species H2O and Ti3+ are at 1 molar concentrations.
