solutions using impressed current from external source. Open circuit potential, potentiodynamic polarization and chronoamperometry test methods were used to assess the corrosion performance of the mild steel in the solutions at room temperature (±25°C) using an AUTOLAB Potentiostat (PGSTAT30. Results show that open circuit potential (OCP) revealed that mild steel specimen in 3.5% NaCl solution has higher tendency to corrode compared to when it is immersed in 1 M H
