- Please excuse my elementry level chemo/physics, but I might have a possible
- clue for you. Leaving out whatever extras might be involved as an
- electrolyte, isn't the deuterium what used to be known poopularly as "heavy
- water"? i.e. water with an extra oxygen atom? If so, the "reaction" would
- seem to be stripping off oxygen one atom at a time as follows:
-
- 1. Starting with h3o one oxygen atom gets stripped off.
- 2. Then with h2o another is stripped off.
- 3. With ho same again.
- 4. Only now would you see a hydrogen atom (bubble).
-
- Hope that helps.....
