Surface Complex Formation Data:

Mineral: amorphous Silica
Reference: SCP21
SCM Type: TL - Triple Layer
Ligand: Cl<1-> - chloride
Site Type: »Si-OH
Equation: »Si-OH + Cl<1-> + H<1+>  ⇔  »Si-OH2<1+>_Cl<1->
LogK: 0.1
Experiment: Potentiometric Titration
Ionic Strength: KCl
Solid/Liquid Ratio: 10.0 g/L
pH Range: 3 - 9
Fit Method: GEOSURF
Comment: 0.001, 0.01, 0.1 M KCl,
This log K value for silica has no effect on the quality of the fit and has been chosen arbitrarily since the exact PZC value for this oxide is unknown;
The equilibrium constants refer to the hypothetical 1.0 M standard state
