Predicting charge of organic compound at certain pH

AI Thread Summary
The discussion centers on the role of pKa and pKb in predicting the charge of organic compounds at specific pH levels. It is established that pKa and pKb are crucial for understanding acid-base reactions, particularly protonation, and are generally sufficient for predicting charges. The conversation indicates a consensus on the importance of these properties, with no counterexamples presented to challenge their relevance. The participants express satisfaction with this understanding, confirming that pKa and pKb are key indicators in this context.

Which property of compounds, organic ones in particular, can help us predict their charge(s) at a specific pH? Is pKa/pKb the only one? I would like some confirmation on this. Thank you very much!

pKa and pKb help predict charges related to the acid/base (mostly protonoation) reactions. As these dominate, pKa/pKb is usually enough.

Actually I can't think of a counterexample ATM. Which probably means I will feel ashamed later today.

This information is enough. Thank you very much!
 

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!!
