Ions are kept in solution by several water molecules, not just one.
Entropy favours reactions with multiple products over those with fewer. I assume that will also play a role. In other words: You have way more water molecules than ions in your solution, statistically speaking your ions will heavily favour the water molecules over other ions.
Everything moves and vibrates faster. That means that bonds will be broken more often and you will reach your ‘final’ state earlier, aka salt dissolves faster. In addition, Ion Bonds require you to stay still more or less (it’s a solid), whereas ions being complexed by water is a fluid state.
This brings us to 2.: Higher temperature further pronounces the effect of entropy, aka multiple ions are preferred over one large crystal.
There may be more to it though!
Two things on this:
Interesting!
And if the solution is hotter, the water molecules have more energy, so they can dissolve more solid solute? Is that what happens?
Heat does two things:
Very interesting!
