Surface Complex Formation Data:

Mineral: Goethite
Reference: SHV08
SCM Type: CDM - (CD-)MUSIC
Ligand: Mg<2+> - magnesium
Site Type: »Fe-singly
Equation: 2 »Fe-OH<0.5-> + Mg<2+> + H2O  ⇔  (»Fe-OH)2<0.29->MgOH<0.29+> + H<1+>
LogK: -6.44 ± 0.07         LogK2.31 nm−2 (SSD-normalized):   -6.29
Experiment: Potentiometric Titration
Ionic Strength: NaNO3
Temperature: 298.15 K
Solid/Liquid Ratio: 20.0 g/L
