The corrosion of iron, copper and brass alloy has been investigated in different medium i.e. HNO3, H3PO4, H2SO4, HCl, CH3COOH. The study reveals that corrosion rate increases in the order iron > copper > brass and for the medium the corrosion follows the order HNO3 > H3PO4 > H2SO4 > HCl > CH3COOH. The rate of corrosion increases with increasing concentration of acid and with increase in time
