Describe the metal solution interface after Helmholtz.
The excess charge of a metal is balanced by ions in solution, analogous to a plate condensator.
Describe the metal solution interface after Gouy-Chapman.
The layer for balancing the charge in the solution has a defined thickness, due to the interplay between electrostatic and thermal forces.
Describe the metal solution interface after G-C-Stern.
