Answer to Question #260975 in General Chemistry for Chizzymelody

Question

What's the electric potential difference between metal and it's solution

Answer 1

Can be called electrode potential

In the case of a metal in contact with an electrolyte solution, the interfacial region consists of an electric double layer. The potential difference between a metal and the solution is almost entirely located across the very thin double layer, leading to extremely large potential gradients in this region.
