Show Detailed Complexation Query Results


Surface Complex Formation Data:

Mineral: Anatase
Reference: JA98
SCM Type: TL - Triple Layer
Ligand: Na<1+> - sodium
Site Type: »Ti-OH
Equation: »Ti-OH + Na<1+> + H<1+>  ⇔  »Ti-OH2-Na<2+>
LogK: -7.7         LogK2.31 nm−2 (SSD-normalized):   -7.36
Experiment: Literature
Ionic Strength:
Temperature: 298.15 K
Fit Method: FITEQL
Comment: log K from RAV94 but there for goethite with other protolysis data »Fe-O<1-> + Na<1+> = »Fe-O-Na logK = 1.2 »Fe-OH = »Fe-O<1-> + H<1+> pK2 = -logK = 8.9 sum »Fe-OH + Na<1+> = »Fe-O-Na + H<1+> logK=1.2-8.9= -7.7
