... "direct reduction", originally proposed by deWaard and Milliams in 1975. An alternative explanation has carbonic acid providing additional hydrogen ions via its dissociation while the dominant cathodic reaction is reduction of hydrogen ions; this mechanism is referred to as a "buffering effect...

... source of hydrogen ions when the concentration of each acid is the same. According to many studies, acetic acid enhances the corrosion rate of mild steel by accelerating the cathodic reaction. The mechanism of acetic acid reduction at the metal surface is still being debated. When the reduction...

... at 25°C ), it is the main source of hydrogen ions when the two acid concentrations are similar. The acetate ions form iron acetate upon reaction with iron Fe + 2HAc Fe(Ac)2 + H2 (2) But, iron acetate s solubility is much higher than iron carbonate s, so protective film formation by iron acetate does...
