People often to PH or total discretion to judge the strength of food corrosive acid, PH or total acid and the corrosive doesn't actually is proportional to the relationship, the types and content of acid corrosion, especially on the walls of the tank corrosion type of influence is greater. Acid corrosion properties and there is a close relationship between the ability of metal ions, formation of complex compound: easy and stannous ions combining with acid can promote the dissolution of tin, which is the strongest with oxalic acid, fumaric acid, citric acid, tartaric acid, Easy and ferrous ion combined with acid can promote the dissolution of iron, with phosphoric acid as the strongest, malic acid, then followed by citric acid, tartaric acid, lactic acid, acetic acid. In addition, the dissociation of PH and organic acids and the formation of complex compound, therefore, PH can affect the corrosion rate, namely the same food, the lower the PH, the faster the corrosion.
