摘要

Piezoelectric resonator measurements in perchloric acid, sodium tetrafluoroborate and sodium sulphatesolutions and comparison with earlier reported measurements in hexafluorophosphate, perchlorate andchloride solutions show that a decrease of interfacial viscosity of anion solutions, when gold electrodeis polarized towards potential of zero charge, is mostly governed by surface charge. At the potential ofzero charge a decrease of interfacial viscosity of all solutions investigated was in the range from 0.5%to 0.8% of the bulk viscosity. Considering that interfacial viscosity is determined by averaging over thedecay length scale of the damped shear wave radiated into the liquid by the resonator, modelcalculations show that the measured changes of average viscosity are caused by changes of the actualinterfacial viscosity and the thickness of the layer, where the change of interfacial viscosity occurs.
