The acid dissociation constant of triethylsilanol in aqueous solution
CHIMIA, 1974 The acid dissociation constant of (C2H5)3SiOH in aqueous solution was evaluated with the aid of a distribution method using CCl4 and an aqueous phase of constant ionic strength as solvents. The experimental results led to a value of pKa = 13.63 (± 0.07)

Thermodynamic formulation on Ostwald’s law of dilution and the acid dissociation constant Ka [PDF]
, 2022 The thermodynamic background of Ostwald’s law of dilution, which gives the acid dissociation constant (Ka), is revealed. The feature of Ka as a constant is understandable in the same context as the equilibrium shift of the gas reaction by pressure.

The Dissociation Constants of Tetrahydrofolic Acid
Journal of Biological Chemistry, 1966 Six dissociable groups exist in tetrahydrofolic acid in the range H0 -3.0 to pH 14. The assignments in tetrahydrofolic acid by titrimetric and spectrophotometric comparisons with model compounds, p-aminobenzoylglutamic acid and 2-amino-6,7-dimethyl-5,6,7,8-tetrahydro-4-pteridinone, are as follows: acidic ionization of amide, pK' 10.5; N5, pK' 4.82; γ ...
