✦ Synopsis

Polarographic behaviour of aqueous ethanol solutions of CuSO, in 0.5 M HzS04 was tested in the range from 0 to 30 vol. oA of ethanol and it was found that Ilkovi& equation is fulfilled throughout the entire range of examined concentrations. The observed diminishing of the limiting current values with increasing ethanol concentration and the appearance of a minimum on the plateau of the limiting current are exulaincd bv the surface activitv of ethanol at the electrode-solution interface, by an increase of the medium viscosity and by salvation.
