AI Thread Summary
Molar absorptivity data for chromate and dichromate ions at various wavelengths is sought, with suggestions for databases like Sadtler mentioned. However, access to relevant data appears limited, as many resources are protected and do not specifically address chromate ions. A recommendation is made to consider conducting personal analysis to generate the necessary absorption curves instead of relying solely on existing databases.

Your posts suggest you will be doing an analysis - why don't you start registering the whole curve by yourself?
 

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!!
