active state

in electrochemical corrosion
@C01351@ in the active state occurs by direct transfer (which may involve one or several steps) of metal ions from the metallic phase to the adjacent electrolyte. The @C01354@ of an active metal usually increases when the @E01956@ is made more positive, other conditions remaining constant.
