Surface Complex Formation Data:

Mineral: Gibbsite
Reference: S05
SCM Type: TL - Triple Layer
Ligand: Na<1+> - sodium
Site Type: »Al-OH
Equation: »Al-OH + Na<1+>  ⇔  »Al-O-Na + H<1+>
LogK: -9.7         LogK2.31 nm−2 (SSD-normalized):   -11.09
Experiment: Literature
Ionic Strength: 1.0 mol/L
Temperature: 298.15 K
Fit Method: Unknown
Comment: calculation from literature values with standard SSA and SSD at ionic strength of 1M »Al-O<1-> + Na<1+> = »Al-O-Na logK = 2.9 »Al-OH = »Al-O<1-> + H<1+> pK2 = -logK = 12.6 sum »Al-OH + Na<1+> = »Al-O-Na + H<1+> logK=2.9 -12.6 = -9.7
