I am wondering if this would work:I need to sublimate compound 1

AI Thread Summary
The discussion revolves around the feasibility of sublimating compound 1, which has a melting point of 175-177°C, from compound 2, with a melting point of 206-208°C, at a temperature of 120°C and atmospheric pressure. Participants highlight the challenges of providing guidance without specific structural information about the compounds involved. There is a suggestion that the compounds are likely organic and have low melting points. Additionally, the importance of preliminary techniques such as recrystallization, titration, or chromatography is emphasized before attempting sublimation.

I am wondering if this would work:

I need to sublimate compound 1 (mp 175-177 C) from compound 2 (206-208 C) at 120 C at atmospheric pressure. Crystals are found and the solids melting point is 150-160 C.

Could anyone help me? I am not completely clear.

Virtually impossible to tell without structure or description of your compound. It is mostly likely organic with a low MP like those. You haven't tried recrystallization, titruation, or chromatography first?
 

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!!

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...
