Anomalous solubility of oxygen in acetonitrile/water mixture containing tetra-n-butylammonium perchlorate supporting electrolyte; The solubility and diffusion coefficient of oxygen in anhydrous acetonitrile and aqueous mixtures

Abstract:

We report the oxygen electro-reduction in air-saturated acetonitrile (MeCN) solution supported by 0.1 M tetra-n-butylammonium perchlorate salt under two experimental conditions: (1) anhydrous MeCN at elevated temperatures from 298.5 to 313.0 K on platinum electrodes; (2) water-mixed MeCN solution (mole fraction of MeCN: 0.72 < χMeCN < 1) at 298.5 K on glassy carbon electrodes. The measurements of diffusion coefficients and concentrations were determined via single and double potential s...
