Standard Potential of t1 t1 222 electrode and stability of t1 222 cryptate in aprotic media
Electrochimica Acta, 1993Co-Authors: Andrzej LewandowskiAbstract:Abstract The Standard Potential, E 0 , of the T1/T1 + and T1/T1 + 222 electrodes (T1 + 222 is the cryplate formed between a T1 + cation and cryptand 222) has been measured in dimethylsulphoxide, N,N-dimethylacetamide, N,N-dimethylformamide, acetonitrile, acetone, sulpholane and propylene carbonate. It has been shown that while the value of E 0 (T1/T2 + ) depends strongly upon the solvent, the E 0 (T1/T1 + 222) is approximately independent of the solvents. The stability constants for the T1 + 222 cryptate and free energies of T1 + transfer between the solvents have been calculated from E 0 (T1/T1 + , and E 0 (T1/T1 + 222) values.

Evaluation of the Standard Potential of the Ag/AgCl Electrode in a 50 wt-% Water-Ethanol Mixture
Journal of Solution Chemistry, 2011Co-Authors: Daniela Stoica, Catherine Yardin, Géraldine Ebrard, Sophie Vaslin-reimann, Paola FisicaroAbstract:This paper deals with the evaluation of the Standard Potential of the Ag/AgCl electrode in a water–ethanol mixture (50 wt-%). A potentiometric method was applied using a cell without liquid junction. Mean activity coefficients of HCl in the same mixture have been also determined. The measurements were performed in the HCl molality range from 0.005 to 0.1 mol⋅kg−1. The Debye–Huckel theory and Pitzer’s model, based on the interactions present in the solution, have been applied. Good agreement was found between the results obtained with the two approaches. Uncertainties of the Pitzer parameters and interionic forces are discussed based on the values found. The variation of the Standard Potential as a function of the temperature was used to calculate the transfer thermodynamic functions. The effects of the solvent composition on the thermodynamic properties of HCl allow to highlight structural changes in water–ethanol mixtures.

Conditional Expectations Relative to a Product State and the Corresponding Standard Potentials
Communications in Mathematical Physics, 2004Co-Authors: Huzihiro ArakiAbstract:For a lattice system with a finite number of Fermions and spins on each lattice point, conditional expectations relative to an even product state (such as Fermion Fock vacuum) are introduced and the corresponding Standard Potential for any given dynamics, or more generally for any given time derivative (at time 0) of strictly local operators, is defined, with the case of the tracial state previously treated as a special case. The Standard Potentials of a given time derivative relative to different product states are necessarily different but they are shown to give the same set of equilibrium states, where one can compare states satisfying the variational principle (for translation invariant states) or the local thermodynamical stability or the Gibbs condition, all in terms of the Standard Potential relative to different even product states.
