Surface Space Charge at the Solid-Liquid Interface

2 Surface Space Charge at the Solid-Liquid Interface 

So far we have only considered the properties of the surface space charge at the solid-vacuum interface. Let us now immerse the solid into a liquid. The molecules in the liquid adsorb onto the solid surface and become polarized as they respond to the electrical field at the interface to produce an electrochemical double layer. They may also line up in preferential bonding directions if they possess a permanent dipole
