mixed potential

The value of the potential of a given electrode with respect to a suitable reference electrode when appreciable contributions to the total anodic and/or cathodic partial currents are made by species belonging to two or more different couples, but the total current is zero, i.e.

$I = ∑ i I i = 0 ( I i ≠ 0 )$

where $I i$ is the partial current of reaction $i$

$I i = I i , a + I i , c$
