and the liydrogen ions in opposite direction from ontside into the 

 boundary layer. 



Let ns now first of all suppose that the internal equilibrium in 

 the metal sets in very rapidly, but not in the hydrogen. This may 

 take place when the metal maintains its internal equililtrium also 

 on rapid emission of ions and electrons, and the internal equilibrium : 



does not set in rapidly enough, so that a gas-phase escapes which 

 contains too many electrically charged particles, i.e. too many ions 

 and electrons or in other words is disturbed in base direction. In 

 this case the three-phase equilibrium: metal phase - boundary 

 liquid - hydrogen phase will be indicated by e.g. the three 

 points d'c'e' . 



When the electrical poiential of the same disturbed hydrogen 

 phase could be measured with regard to the electrolytes of other 

 hydrogen-ion concentrations than c', the line b' c' would denote the 

 electrolytes which can coexist with the same disturbed hydrogen 

 for different electrical potentials. 



We shall now consider the case that the internal equilibrium sets
