Measuring the weight of a electrode is the proof. Magnesium corrodes into a lower energy state. This lower energy state decays from the metal or falls apart. If you have metal falling apart it should be getting lighter. I have seen metals do this, like for example alum and water cells that have been shorted out for a certain time will break apart the magnesium ribbon. Or i have seen aluminum foil get holes in it, if holes are created the metal is getting lighter. magnesium carbonate is white, the electrodes gaining weight are black. White magnesium means its corroding into it lower energy state of its salt forum so it turn white. When it turns black it suppose to be another form of corrosion but i'm not seeing it being destructive like the white corrosion. I'm just saying not all corrosions are the same.
