AI Thread Summary
To oxidize suspended elemental sulfur to sulfate in a solution, raising the pH to 11 and using an excess of hydrogen peroxide is recommended. At this elevated pH, hydrogen peroxide exhibits high reactivity, so it should be added cautiously to avoid any adverse reactions. For further insights and detailed methodologies, a reference link to a relevant article is provided.

Try raising the pH to 11 and using hydrogen peroxide in excess. At that pH peroxide is very reactive so add it very carefully.

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!!
