Electrochemical impedance spectroscopy was used to investigate redox behaviour of moisture containing LiCl–KCl eutectic melts at tungsten and uranium electrodes. Complex impedance plots recorded at uranium electrode were complicated by competing process of adsorption of OH\(^{-}\) leading to large capacitive contribution. This was explained on the basis of resistance due to formation of hydroxide film on surface of uranium electrode that inhibited anodic dissolution of uranium. Complex impedance plots were fitted to different equivalent circuits and variation in redox behaviour was explained.
