The rate of electroplating of steel in acidified CuSO4 solution in absence and presence of isopropanolalcohol were studied by measuring the limiting current. It found that the rate of electroplating wasdecreased in presence of alcohol. The rate of inhibition rang from 40% to 66% depending on theconcentration of alcohol. Thermodynamic properties Ea, H*, S*and G* were calculated. The value-1 of Ea < 42 kJ mol.l , which indicate that, reaction, is diffusion controlled.
