Show Detailed Complexation Query Results


Surface Complex Formation Data:

Mineral: Quartz
Reference: S05
SCM Type: TL - Triple Layer
Ligand: NO3<1-> - nitrate
Site Type: »Si-OH
Equation: »SiOH + NO3<1-> + H<1+>  ⇔  »SiOH2-NO3
LogK: 0.1
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 »Si-OH2<1+> + NO3<1-> = »Si-OH2-NO3 logK = 2.3 »Si-OH + H<1+> = »Si-OH2<1+> -pK1 = logK = -2.2 sum »Si-OH + NO3<1->+ H<1+> = »Si-OH2-NO3 logK= 2.3-2.2 = 0.1
