The electrochemical behavior of tin metal was studied in some inorganic acid solutions; HCl, HNO₃, H₂SO₄ and H₃PO₄, using the open circuit potential measurements and the potentiodynamic polarization technique. In addition, the metallographic structure of tin electrode was examined before and after immersion in test solution by using scanning electron microscope (SEM). The identification of the elements presented in the surface of specimen after immersion in different solutions was performed using an energy dispersion X-ray analysis(EDAX). The obtained results demonstrated that the aqueous dilution of HCl, H₂SO₄ and H₃PO₄ retarded the corrosion of tin electrode, (hydroxyl ion plays a part in basic salt formation), while dilution of HNO₃ acid accelerated the corrosion. It is evident from SEM image that, there were grain boundaries and the surface was more active and rougher in case of mechanically polished electrode. In non-polished electrode, the surface was covered with a protective layer; generally SnO₂. In potentiodynamic polarization study, the formation of basic salt Sn(OH)Cl was  preference to any other oxide in HCl solutions. The increase in NO₂ concentration was responsible for the increase in the rate of dissolution in HNO₃. The tin dissolution in sulphuric acid occurred through an intermediate of (SnHSO₄OH) species.
