AI Thread Summary
The discussion centers on the presentation of solubility, which is typically expressed in grams per volume or moles per volume, but NIOSH uses a percentage format. Participants seek clarification on the meaning of this percentage and express a need for reliable sources that explain NIOSH's definitions. There is a consensus that it is essential to refer to NIOSH for their specific definitions and guidelines regarding solubility in percentage terms. The conversation highlights the importance of understanding different units of measurement in occupational safety and health contexts.

Usualy solubility is presented in grams per volume or mols per volume but NIOSH indicates in percentage? Where can I find a reliable source that explains what does this mean?
 
Chemistry news on Phys.org
It is up to NIOSH to define what they mean.
 
Yes, and they defined it? Perhaps I didn't searched well enough..

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!!
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...
