Abstract: The variation of metal corrodibility, solution corrosiveness and corrosion rates for mild steel in 1 N H2SO4 acid, as a function of time have been studied using gravimetric (planned interval test) and electochemical methods. A new voltammetric method has been developed to determine the corrosion rates at short time intervals. The results of the corrosion of mild steel in 1 N H2SO4 with and without polyvinyl glycol (PVG) inhibitor at short time intervals have been reported. The corrosion inhibition efficiency of PVG is 91 % after 24 h. Significantly, it has also been possible to determine simultaneously the corrosion rates with respect to Fe(II) and Fe(III).
