Electrochemical Series; Corrosion Reaction Comparison

Default reactions are shown (nickel and gold). To select other reactions, please make a choice from the Electrochemical Series.

Anodic Reaction

Ni²⁺ + 2 e^-

This is the oxidation reaction.

Nickel will corrode to populate the electrolyte with Nickel ions.

e^-
electrons conducted
through metal substrate

Cathodic Reaction

Au⁺ + e^-

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.

The driving potential between the two reactions is 1.9 Volts provided the dissolved species Au⁺ and Ni²⁺ are at 1 molar concentrations.
