Abstract

The electrochemical dissolution of mild steel in hydrochloric acid and sulphuric acid by a.c. has been studied. It has been found that with sine wave a.c. (50 Hz) the dissolution efficiency increases with increase in concentrations of the acids and decreases with the progress of electrolysis. As current density increases an initial increase in the efficiency was noticed; but as current density increases further, the efficiency falls. With square wave a.c. of low frequency (0.5 Hz), the dissolution efficiency increases with increasing concentrations of the acids and also with increasing frequency. However the efficiency decreases with increasing current density and time of electrolysis.
