• This work presents the electrochemical study of YbCl 3 in molten CsCl in the temperature range 973–1073 K. Transient electrochemical techniques have been used in order to investigate the reduction mechanism, transport parameters and thermodynamics properties of the reaction YbCl 2 + 1 / 2 Cl 2 = YbCl 3 . The results obtained show that the reduction reaction Yb ( III ) + e ¯ ⇔ Yb ( II ) is reversible being controlled by the rate of the mass transfer. The diffusion coefficient of [ YbCl 6 ] 3 - complex ions was determined. The apparent standard electrode potential of the soluble–soluble redox system Yb 3 + / Yb 2 + was obtained by cyclic voltammetry.
