Yet no one to this day can explain solubility curves of common salts in water.Why only so many grams of this salt dissolve in water at this temperature. No one knows.Models boil down to "polar likes polar"
Because the more your balls are vibrating the more space there is between them to fit other balls
>>17030043are you suggesting something...
[math]ΔGsol=ΔHsol−TΔSsol[/math]
>>17030027>>17030287it's true that some stuff remains unclear though, for example the exact mechanism of the entropic params like Hofmeister series ions (though it seems to have to do with the hydrophobic effect on non-polars / surface tension, which is also quantum fuckery)By comparison the enthalpic params (lattice and hydration energies) are well-understood
>>17030287>promotes, enhancesYet no model that can predict actual solubility
>>17030371You can approximate or statistically infer the entropic params, but it's not something you can calculate without molecular simulations, no. Because quantum fuckery. That's not the same as "no one knows why"Enthalpic params are fairly straightforward closed form Coulombic equations though.
>>17030436>That's not the same as "no one knows why"Fact is no model, including simulations, predicts solubility.I dont dismiss simulations, a complex model doesnt have to take the shape of a beautiful algebraic formula, the math might simply require billions of calculations. Thats still a model, yet it doesnt exist for this.
>>17030437Nta but nobody wants to make a "model" for something that's so computationally intractable.
>>17030436>Enthalpic paramsthis doesn't exist, you just made this up
