My Observations
1. The amount of particulate is extreme and has a dark almost black appearance.
2. CLR does NOT cleanup the plates worth a darn.
3. The Positive(?) plate is eroded pretty badly. The erosion is most notable along the plate edges and pitting pretty bad on the side of the plate facing the negative plate.
4. The gunk even blackens the CLR.
5. The temperature electrode was pitted as well.
6. I suspect if there ever was a candidate for Cr(VI) or Hexavalent Chromium reduction, this sample is it. The mere evidence of erosion of one of the plates is proof enough that there is significant chromium in the particulate.

Was the correded plate connected to th epostive or negative aspect of voltage source. Do you think that thge correded plate made more hydroxy gas as to the other plate.
Wonder what the outcome would be with a neutral plate sandwiched between those two? I keep posting but never see the post-must be something I am doing wrong.
I'm not certain which plate was which, but it seems to me the corroded plate was on the positive side. Since Oxygen is the corrosive element between hydrogen and oxygen this stands to reason although I can't rule out another compound or element as the culprit in this case. I'm not planning to find out though since it makes too much of a mess and ruins the equipment.
Due to the nature of hydroxy production, oxygen is attracted to the positive plate and hydrogen is attracted to the negative plate. I doubt there was more production due to the corrosion. If anything there may have been less oxygen released because it combined with the elements in the plate instead of forming gas.
What I think we would find with a neutral plate is corrosion occuring on one side of the plate and not the other. Corrosion on the neutral plate edges is problematic and could provide circumstantial evidence of edge leakage dynamics when using a plate configuration incorporating neutral plates.
The last statement sounds like the basis for another experiment! Unfortunately, I'm not going to like the cleanup and waste.

Sounds like a good reason to encase the whole plate system in shrink tubing when using the smack booster setup/configuration.Edge leakage dynamics-a whole new ball game seems to be evolving.
