AI Thread Summary
The discussion focuses on the growth of anodic porous aluminum oxide on aluminum surfaces through electrolysis, specifically addressing the differences between galvanostatic and potentiostatic electrolysis. In galvanostatic electrolysis, the current is maintained at a constant level, which means that the potential is adjusted dynamically to ensure that the current remains steady. This results in a direct relationship between charge and time, expressed as q = i*t, where q is charge, i is current, and t is time. Understanding this concept is crucial for effectively controlling the anodization process and achieving desired characteristics in the aluminum oxide layer.

hi.im studing a topic concerning the growth of anodic porous aluminium oxide on aluminium surface by process called electrolysis.during this I am confused about galvanostatic and potentiostatic electrolysis. please help me in understanding the concept behind galvanostatic reigm. ?

You change potential in such a way that current is constant. That means q (charge) is always i*t (current times time).

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!!
