"Хімічне розчинення" металів як результат відхилення від принципу незалежності перебігу суміщених реакції

Abstract

The new alternate explanation of a nature of anomalous (chemical) metal dissolution was given. It was shown that anomalous dissolution can be considered as anodic metal ionization if near electrode layer рНS take into account. This rule is true for high negative potential region. Near electrode layer рНS increase by one unit when potential shifts on 0.059 V in negative direction. Corrosion metal potential also shifts on 0.059 V in negative direction when value of solution pH increase by one. If this two effects take into account one can obtain a compensation effect external manifestation of which will be independence of metal ionization rate from applied potential in a certain cathodic region.
