This research work investigated the corrosion rate of cold worked mild carbon steel in Hydrochloric acid, Nitric acid, Acetic acid, Hydrogen tetraoxosulphate (VI) acid, and phosphorus acid, to determine the corrosivity of each of the acids, and susceptibility cold worked mild steel to corrosion in the used environment, using weight loss measurement approach. The coupons were measured prior to immersion and different weight measurement taken at interval of 24 hours, over the period of 168 hours. The difference in weight between the original weight and the weight at each 24 hour interval (weight loss), was estimated and used for calculating the corrosion rates. The results obtained showed that t HNO3 is more aggressive in all the five acids considered.
