| Abstract | ||
| This research involves study effect of halogen ions presence in 0.2M sodium sulphate on the corrosion of brass at room temperature (30oC). Three concentration of halogen ions (Fˉ, Clˉ, Brˉ, and Iˉ) were used 0.1, 0.2, and 0.3 M. The different in corrosion parameters before and after added the halogen ions interpreted and discussed which involves corrosion potentials (Ecorr), corrosion current densities (icorr), and Tafel slops (bc & ba) in addition to discuss the polarization curves. Polarization resistances (Rp) and the change in free energy (ΔG) were calculated and interpreted, in addition to calculate the rate of corrosion (Rmpy). The results of this work indicates that the presence of halogen ions in experimental solution increases the rate of corrosion, and the effect of halogen ions follows the sequence to increase the corrosion Iˉ > Clˉ > Fˉ > Brˉ. | ||
