AI Thread Summary
As temperature rises, the solubility of gases in liquids decreases due to increased kinetic energy at the surface of the liquid. Higher temperatures allow more gas molecules to escape from the liquid into the atmosphere, while fewer gas molecules return to the liquid through condensation. This dynamic results in a net loss of gas solubility as the temperature continues to increase.

As temperature increases, the solubility of gases decreases, but why?

Evaporation and condensation occurs primarily at the surface. As temperature increases the kinetic energy at the surface increases and more molecules have a chance to escape rather and less to condensate.

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!!
