The effect of Piper Betel leaf extract and the mixture of various concentrations of KI on corrosion of mild steel in 0.1M, 0.5M and 1.0 M HCl have been investigated using weight loss methods. The study revealed that mild steel is more efficiently inhibited by P. betel leaf extract in the presence of KI than pure extract of P. betel leaves. The inhibition efficiencies increased with increased concentration of the additives. The highest inhibition efficiency of 64.20% was observed with single Piper betel extract. An improved inhibition efficiency of 88.92% was observed with the mixture of leaf extract and KI in 0.5M HCl. Inhibition efficiency decreased with increase in temperature an effect attributed to synergism between Piper betel leaf extract and KI.
