    Helium Source
AI Thread Summary
The regulated helium source in HPLC serves primarily to degas solvents, ensuring that dissolved gases do not interfere with the analysis. Additionally, it creates a protective blanket of helium over the solvent reservoirs, preventing air from re-dissolving into the solvents. This dual function enhances the accuracy and reliability of HPLC results by maintaining solvent purity and stability.

What's the purpose of the regulated helium source going into the solvent reservoirs in HPLC? Is it just to degas the solvents? Does it have any other use?

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!!
