AI Thread Summary
The discussion centers on the relationship between the concentration of one solute in a solution and its impact on the solubility and dissolution rate of another solute. It confirms that the presence of one solute can indeed affect the maximum amount of another solute that can dissolve, particularly in non-ideal mixtures. The common ion effect is mentioned as a simple case, but there is a lack of comprehensive models to predict behavior in more complex scenarios, suggesting reliance on experimental data. The conversation also touches on the design of an acetone evaporator for thermal management, highlighting concerns about the influence of humidity on its effectiveness, especially during summer months. The engineering approach discussed leans towards trial and error, questioning whether the air directly contacts the acetone or if a heat exchanger is used to separate the two.

Does the amount of one solute in a solution effect the maximum quantity of another solute that can be dissolved ino that solution, or the rate of dissolution?
To provide context: I'm thinking of making an acetone evaporator for thermal management purposes. I'm wondering if the humidity of the intake air would be relevant in the effectiveness of the cooler, especially since I would mostly be using it in the summer, when the air is remarkably humid here.

Short answer: yes, it does.

But apart from relatively simple cases (common ion effect) I am not aware of any model describing the behavior of such solutions, and intuition tells me even if they exist (highly probable) they are heavily relying on experimental parameters (as most models dealing with non-ideal mixtures do).

Hopefully I am wrong.

Hmm, so I'm SoL when it comes to predicting the effectiveness of my acetone heat rejector? I love the 'build it and hope for the best' method of engineering. It's my favorite.
 
Does the air contact the acetone directly, or is there a heat exchanger with with acetone evaporating on one side of a wall and air cooling on the other side?
 
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!!
