Sodium sulfate (Na2SO4) is corrosive to aluminum when used as an electrolyte in water during electrolysis. It does not directly "eat away" at aluminum but instead forms a protective film of oxide or hydroxide on the aluminum surface while the sulfate ions bind to the metal. This interaction can lead to corrosion over time, affecting the integrity of submerged aluminum components.

Will Na2SO4 (Sodium sulfate), when used as an Electrolyte in Water, EAT away at submerged Aluminum components, when performing Electrolysis ?
Do the published values of Enthalpy include the work done against a constant pressure, e.g., the atmosphere? (I am not a chemist). I am reviewing enthalpy and entropy as part of the statistical mechanics applied to transistors. I assume, from my reading, that the work done would mostly apply to reactions involving gasses.
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!!
