Anodic Reaction |
|
|
|
Ni
 Ni2+ +
2
e- |
|
| This is the oxidation reaction. |
|
Nickel will corrode to populate the electrolyte with Nickel ions.

|
Cathodic Reaction |
|
|
|
|
Au+ +
e-
Au |
|
| This is the reduction reaction. |
|
Gold ions (if present) will be removed from the electrolyte and plated onto the cathode surface as they accept conducted electrons.
|
