On the other hand, hypochlorous acid/hypochlorite (or hypobromous acid/hypo-bromite, HOBr/OBr–) can be formed by the action of chlorine (or
CORROSION BASICS

The Nernst equation allows us to calculate metal potentials under differing metal ion or oxidation/reduction conditions. The Nernst equation may be stated as follows: [ ] [ ] [ ]

High-Performance Alloys for Resistance to Aqueous Corrosion
www.parrinst.combecomes anodic while the more noble becomes cathodic. The anodic material actually protects the cathodic leading to its own accelerated decay. Ranking of materials in an electromotive force (EMF) or galvanic series in a specific media will help determine the propensity of two materials for this type of corrosion. The farther apart the materials
