Is PVDF a Suitable Alternative to Teflon for Iodine Experiments?

AI Thread Summary
The discussion centers on the need for valves made from Teflon for an experiment involving iodine, with a tight deadline for delivery. The user has found that some suppliers offer PVDF valves and fittings, which are reported to be resistant to iodine up to 65°C. There is uncertainty about the comparative resistance of PVDF to iodine versus Teflon. The user is seeking recommendations for immediate alternatives, as Teflon products are not readily available. The mention of specific suppliers like Cole Parmer highlights the search for accessible options that meet the required specifications for the experiment.

I am working with Iodine in our lab and we typically use Teflon, but for an experiment we might need all the valves in such a material. Yet, a few places that I have found that carry such products are not on hand and would be available in weeks.

I would like something by Monday/Tuesday. However,some places that carry a lot of Teflon products have PVDF valves and fittings available. Cole Parmer and few other places say PVDF is resistant to Iodine, but I am not sure how much compared to Teflon.

Any suggestions?

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!!
