potential-determining (p.d.) ions

https://doi.org/10.1351/goldbook.P04776
Those species which by virtue of their electron distribution between the solid and liquid phase (or by their equilibrium with electrons in the solid) determine the difference in Galvani potential between these phases. This definition requires that adsorbed p.d. ions are part of the @A00153@ and belong to the category of @S06180@.
