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+> + NO2<1-> = »Si-OH2-NO2 logK = 5.1 »Si-OH + H<1+> = »Si-OH2<1+> -pK1 = logK = -2.2 sum »Si-OH + NO2<1->+ H<1+> = »Si-OH2-NO2 logK= 5.1-2.2 = 2.9
