Effects of using a synthesized aminothiazole (BZ) Schiff base at different concentrations with and without the addition of 1 mM of KI on the corrosion mitigation of mild steel (MS) in 0.5 M sulphuric acid (H₂SO₄) solutions are studied electrochemically using direct and alternating currents (DC and AC) techniques. Besides, the adsorption and thermodynamic parameters are calculated in a temperature range of 293–323 K. Furthermore, Mott‐Schottky analysis is used to study the type of oxide layer on the MS surface. Quantum chemical calculations and Monte Carlo simulation techniques are used, and both confirmed the experimental results.
