    Analysis budget
AI Thread Summary
The discussion centers on the need for budget estimates for geochemical analysis of water and sediments, specifically focusing on the costs per sample for Tributyltin Oxide (TBT), Per- and Polyfluorinated Alkyl Substances (PFAS), and Pesticides. The original poster, Roberto da Silva, is seeking information on the individual costs of these analyses and resources for updated pricing in Europe and the USA. The conversation highlights the importance of obtaining accurate budget information for these specific environmental contaminants to aid in the preparation of a report.

TL;DR Summary
Does anyone know, or can anyone point me where can I check out budgets for TBT, PFAS and Pesticides analysis on soil/sediment samples?
I need to do a brief report, introducing geochemical analysis on water and sediments, and its asked for Budgets (per sample) for analysis on Tributyltin Oxide (TBT), Per- and Polyfluorinated Alkyl Substances (PFAS) and Pesticides. Does anyone know how much those three would cost individually (per sample)? Or where can I check for updated budgets in Europe or USA?
I appreciate any help given on this subject.
Thanks,

Roberto da Silva

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!!
