Thermodynamics Of Ionization

The ionization constant, K, of trans-crotonic acid, and the first and second ionization constants, K1 and K2, of adipic acid have been determined in water at seven different temperatures ranging from 15 to 45 °C with the help of the cells without liquid junction using silver – silver chloride and quinhydrone electrodes. The variations of pK, pK1, and pK2 with temperature have been expressed by the equations[Formula: see text]and[Formula: see text]From the temperature coefficient of the ionization constants, the standard enthalpy, entropy, Gibbs energy, and heat capacity changes of the corresponding dissociation processes have been calculated. Using the values of ionization constants of adipic acid, the standard potential of the Ag(s)/Ag2Ad(s)/Ad2− electrode, and the related standard thermodynamic quantities for the electrode process[Formula: see text]have been calculated in water at those temperatures.

The first and second ionization constants of phthalic acid have been determined, in formamide, at temperatures ranging from 5� to 45�C at 5� intervals, with the help of cells without liquid junction using quinhydrone and silver-silver chloride electrodes. By means of the Bjerrum equation, the distance r between the acidic groups has been estimated in formamide at different temperatures.

The first and the second ionization constants of phthalic acid have been determined, in formamide, at 25� with the help of cells without liquid junction using quinhydrone and silver-silver chloride electrodes. The values of pK1a and pK2a were found to be 4.214�0.02 and 7.716�0.01, respectively, at this temperature.

Electromotive force measurements of cells without liquid-junction containing hydrogen electrodes and silver – silver chloride electrodes have been used to derive the dissociation constants of acetic acid and solvent water – ethylene glycol mixtures (50 and 70 mass % of ethyleneglycol) at 14 temperatures from −35 to 30 °C. Primary acidity standards related to these acetic buffered and sodium hydroxide solutions are given.

High-definition transcranial direct current stimulation (HD-tDCS) is a promising non-invasive neuromodulation technique, which has been widely used in the clinical intervention and treatment of neurological or psychiatric disorders. Sintered Ag/AgCl electrode has become a preferred candidate for HD-tDCS, but its service life is very short, especially for long-term anodal stimulation. To address this issue, a novel highly durable conductive carbon/silver/silver chloride composite (C/Ag/AgCl) electrode was fabricated by a facile cold rolling method. The important parameters were systematically optimized, including the conductive enhancer, the particle size of Ag powder, the C:Ag:PTFE ratio, the saline concentration, and the active substance loading. The CNT/Ag/AgCl-721 electrode demonstrated excellent specific capacity and cycling performance. Both constant current anodal polarization and simulated tDCS measurement demonstrated that the service life of the CNT/Ag/AgCl-721 electrodes was 15-16 times of that of sintered Ag/AgCl electrodes. The much longer service life can be attributed to the formation of the three-dimensional interpenetrating conductive network with CNT doping, which can maintain a good conductivity and cycling performance even if excessive non-conductive AgCl is accumulated on the surface during long-term anodal stimulation. Considering their low cost, long service life, and good skin tolerance, the proposed CNT/Ag/AgCl electrodes have shown promising application prospects in HD-tDCS, especially for daily life scenarios.
