Show Detailed Complexation Query Results


Surface Complex Formation Data:

Mineral: Quartz
Reference: S06c
SCM Type: TL - Triple Layer
Ligand: Ca<2+> - calcium
Site Type: »Si-OH
Equation: 4 »SiOH + Ca<2+> + H2O  ⇔  (»SiOH)2-(»SiO<1->)2-Ca(OH)<1+> + 3 H<1+>
LogK: 0.4
Ionic Strength: 1.0 mol/L NaCl
Temperature: 298.15 K
Fit Method: Unknown
Comment: refer to the reactions shown producing the surface species from »X-OH and H2O, and were generated by regresssion of the data in Figs. 1-6 (see text) using the model parameter summarized in Table 1 (see text; entered in RES³T "Site Density & Surface Protolysis"); source of surface charge data: [R83]; reaction equation in the given article probably wrong, because in the text an alternative reaction product is given
