Electrocapillary Curves of Chloride Ions in Water-Hydrogen Flouride Mixtures

Abstract

We have determined the electrocapillary curves of the mercury electrode with a mixture of hydrogen fluoride and water contaning 40% (by weight) of HF, using the mercury electrode drop time formation technique. The addition of KCl at concentrations from 0.01 to 0.5 M provokes a displacement of the electrocapillary curves showing a possible specific adsorption of HCl at the electrode.
