We calculated the diffusion impedance to the surface of a rotating disk in an Ostwald fluid. The experimental study has been performed by a frequency analysis of the electrochemical impedance corresponding to the reduction of the potassium ferricyaaide in a KC1 (N) solution ofa high polymer additive
