Water-based electroneutrality

Please login with a confirmed email address before reporting spam

I'm trying to model an electrochemical reaction using the water-based electroneutrality, because H+ and OH- are among reactants. Comsol automatically adds these species to the electrolyte definitions node, but how to address them in the reaction? cH or cOH return the error 'unknown variable'.

Perhaps you can try using supporting electrolytes and adding OH and H electrolytes for equilibrium reactions
