The charge-balance of a hydrated clay will also depend on the ratio of mineral surface volume to fluid volume, but in the case of fine clay minerals used medicinally (e.g. in a poultice), the surface area of the mineral is generally large enough to control (buffer) the fluid pH. The mineral assemblage in this case has the greater effect on attractive forces to the bacterial surface.
