    stainless steel are immersed in a sulphuric acid solution and are taken through a current‚ it may be observed that corrosion products are formed around the electrodes‚ to differing degrees. The reason for this is because when a uniform voltage is applied across the series of interconnected electrodes in the acid solution different potentials are obtained at each electrode and hence different electrochemical reactions take place. The products of these reactions can be identified by using complex ion
