| Outline of Final Research Achievements |
The electrochemical properties of hydrophilic ionic liquid-water mixtures were investigated. An anodic current appeared when slight water was added to the ionic liquid. This peak was increased with water concentration and the slope of the increase of the peak area was changed around 10wt% water concentration.
The solution resistance was also changed around 10 wt%. In the case of thiol-modified electrodes, the resistance was increased because the reactive anion suffered steric repulsion.
Hydrogen bonds between water molecules were observed in even slight water concentration, and these are strengthened with water increasing.
