Dissolving is a two step process. How does the nature of these individual steps combine to determine whether the overall process will be enodthermic or exothermic?
...and me, I have no idea..

You have to consider the lattice enthalpy of the solute (energy required to break its ions apart) and the hydration enthalpies of the constituent ions, both positive and negative, added together. If the lattice enthalpy outweighs the hydration enthalpies, then the substance will tend to be insoluble because the overall process will be endothermic.

OK, I'll give it a shot, first, I'll go get a coke, be right back....have any Coke points you don't use?
OK, exothermic is from outside the organism and endothermic is from within. SO, it would be the molecular base and it's point of origin to determine this issue.
We are endothermic, most fish are exothermic, we are a product of our enviorment.
Since in nature, only the fittest survive, a waterfall will wear away the rock.
I think endothermic have it over exothermic unless you fall off a crab boat in the middle of the Bearing Sea.
I probably didn't answer your question, but I gave it a try!
Have a great day.

I think you're breaking ionic bonds between the atoms in the molecule that's dissolving, and forming ionic bonds between these atoms and the solvent. I would guess that whether it's endothermic or exothermic would depend on the energy it took to break the old bonds and the energy released in forming the new ones.
