Mixtures of strong electrolytes in aqueous solution. Viscosity A- and B-coefficients of mixtures of tetramethylammonium and potassium bromides in aqueous solution at different temperatures and the energy of activation for viscous flow

Electrochimica Acta

The viscosities of aqueous solutions of several, α, β and γ-amino acids at three different pH's have been measured at temperatures between 30–40 °C in the concentration range 0.005 to 0.1 molai, and the B-coefficients have been calculated using the equation η/η0 = 1 + Bc. The corresponding activation energies for viscous flow have been calculated with the help of the Feakins, Freemantle and Lawrence equation. The S-coefficients for all the amino acids at the three pH's follow the sequence B(inH2o) &gt; B(in NaOH) &gt; B(in HCL) over tne above temperature range. The gradual decrement of B-coefficients from water to HCl has been discussed in terms of decreasing electric field of the ions concerned. From the temperature coefficient of B it has been inferred that the simultaneous influence of polar and non polar parts is responsible for the extra structure enhancement by the γ-amino acids in aqueous solution. © 1982, Akademische Verlagsgesellschaft, Wiesbaden

Ion solvent interaction of amino acids

The viscosities of d/-a-Alanine at three different pH's have been measured at 35° and 45° C and the ß-coefficients have been calculated using the equation ŋ/ŋ0 = 1 + Be. The corresponding activation energies for viscous flow have been calculated with the help of the Nightingale- Benck equation. The effect of ionic charge on the ß-coefficient of -Alanine in its three different ionic forms has been discussed on the basis of ion-solvent interaction. © 1980, Akademische Verlagsgesellschaft, Wiesbaden
