Electrolysis and drift currents

AI Thread Summary
In electrolysis, a positive and negative drift current exists between the electrodes due to the separation of charges as electrons are removed from atoms. It is not feasible to have only one type of drift current, as the accumulation of positive charge would eventually halt the electrolysis process if positive ions are not removed. While lighter electrons can move easily in response to an applied potential, heavier positive ions cannot move as freely, emphasizing the necessity of maintaining both positive and negative drift currents for the electrolysis to continue effectively.

Hi,
If there is an electrolysic in a vat, there is a positive and negative drift current betwwen the electrodes.
Is it possible to have a situation where there is only one (either positive or negative) drift current?
Thanks

I don't think so, because in electrolysis you're ripping electrons off of their atoms. This results in a separation of charges and if you don't pull the positive ions away you'll quickly run into a situation where the positive charge buildup is so large that you can no longer pull any electrons away, stopping the electrolysis process.

But in a conductor, if we apply a potential suddenly, the light electrons can move easily but the heavier positive ions cannot.
 
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...
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!!
