Quantum mechanics investigation of acid dissociation constant of carboxylic acids in aqueous solution
According to the Bronsted definition, any compound which has a hydrogen atom is an acid, since itmay be lost as a proton. A thermodynamical cycle is proposed to calculate absolute pKa values forBronsted acids in aqueous solution. The equilibrium of dissociation of a Bronsted acid depends onthe interaction of the acid and its conjugate base with solvent molecules. There fore the pKa valuedepends...
متن کاملThe Vibration Spectra of Hydrazoic Acid, Methyl Azide, and Methyl Isocyanate The Thermodynamic Functions of Hydrazoic Acid
The vibration spectra of hydrazoic acid, methyl azide, and methyl isocyanate have been investigated in the spectral region between 2 and 20~. Correlation of the spectra of these structurally similar molecules has made possible the determination of all the fundamental frequencies of hydrazoic acid and all but the methyl torsion frequency in the methyl compounds. From these fundamental frequencie...

متن کاملDetermination of acid dissociation constant of degradable tetrabromophenolphthalein ethyl ester by capillary zone electrophoresis.
An acid dissociation constant of tetrabromophenolphthalein ethyl ester (TBPE) was determined through the measurement of electrophoretic mobility by capillary zone electrophoresis (CZE). Although TBPE is degradable in acidic pH region and it gradually degraded at pH conditions around and below its pKa values in the time scale of the CZE measurement, equilibrium species of interest were detected ...
متن کاملFirst Dissociation Constant of Succinic Acid from 0° to 50° G and Related Thermodynamic Quantities
The sensitivities of CH4 and CD4 differ by about 2 percent and are probably equal within the experimental uncertainty. The total ionization is apparently the same for CH4, CH3D, and CH?D2. The low value for CHD3 is not significant in view of the uncertainty in this spectrum. The difference in the total ionization of CH4 and CD4, however, is greater than the estimated error; and since the number...
