Coupons of dimension 5.0 cm x 4.0 cm were immersed in test solutions of uninhibited acid and also in those containing various amount of BKS (10, 25 and 40 %v/v) at 30 oC and 60 oC respectively. The results showed that the extract addition reduced mild steel corrosion in the acidic media. The inhibitive efficiency of 92.07 % was attained at 40 %v/v in 1 M H2SO4 at 30 oC temperature, while the efficiency of 89.19 % was realized at the same concentration in 1 M HCl at 60 oC temperature. Hence, BKS can be considered as a good and safe inhibitor against mild steel corrosion in both acidic media.enBitter Kola StemInhibitionCorrosionWeight lossMild SteelArticle
