AC Electrical heating - Clay sediments

AI Thread Summary
Electrically heating clayey soils with high moisture content and salt solutions raises concerns about electrolysis when using AC currents at 230 V and 60 Hz. The process of electrolysis can occur, leading to the production of gases and other byproducts, which may be problematic depending on the project's goals. However, the method of applying electricity through wires rather than directly inserting electrodes into the soil alters the dynamics of electrolysis. Understanding these differences is crucial for evaluating potential risks and effects on the project.

I am working on a project involving electrically heating clayey soils (having 55% moisture content and 0.5 M salt (nacl/KCl) solutions in the pore space.

Does anybody know if electrolysis of water/electrolyte is a concern with AC currents (230 V, 60 Hz frequencies)?

Thanks,

"A concern?" You mean "will electrolysis of water and salts take place?" Yes. If that concerns you, then it is a concern. If the electrolysis products are a concern, yes, also.
 
However, electrolysis requires sending electricity through the water. You're talking about sending electricity through wires in the water. Not the same thing.

He didn't say he was just shoving electrodes into the ground, did he --- duh.
 

Thread 'Solubility of MgSO47H2O in water'

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
