Effect of Electrolyte Concentration on the Viscosity and Voltammetry of Supercritical Solutions AbbottAndrew P. HopeEric G. J. PalmerDonna 2005 The viscosity of a supercritical electrolyte solution is measured for the first time using a modified quartz crystal microbalance, and it is shown that ionic solvation leads to a significant structuring of the solvent and an appreciable increase in solution viscosity. Voltammetric investigations in the electrolyte solutions are used to confirm the magnitude of the viscosity changes, and these account for the appreciably lower than expected peak currents.
