How to Calculate CO2 Saturation Levels in Saline Water?

AI Thread Summary
To express the saturation level of a system of dissolved CO2 in oversaturation, calculate the difference between the molar fraction of CO2 in the starting mixture and the molar fraction in the equilibrium mixture. This method provides a clear understanding of the amount of CO2 that escapes after reaching equilibrium, allowing for a precise assessment of the saturation level in the system.

i am studying a system of dissolved CO2. it is in oversaturation, and NOT in equilibrium. but i don't know how to express its saturation level. all i know is the molar fraction of CO2 that escapes after reaching equilibrium. how can i calculate that?

The same way you'd calculate anything else; composition of starting mixture/solution minus composition of "equilibrium" mixture.
 

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!!
