Question

state the relation between reduction electrode potential of metal electrode and its tendency towards corrosion​

Answer 1

Answer:

Reduction Potential

The more positive the potential, the greater the species' affinity for electrons, or the more the species tends to be reduced. Oxidation-reduction in a galvanic cell: In this galvanic cell, zinc reduces copper cations. The reaction yields zinc cations and neutral copper metal.

Answer 2

Answer:

The one with the highest reduction potential will be what you want to select as the reduction half-reaction and therefore be your cathode. The one with the lowest reduction potential will be what you want to select as the oxidation-half reaction and therefore be your anode.
