- Why do salts such as NaCl dissolve? 3 answers
In the case of water dissolving sodium chloride. I was under the impression that hydrogen bonds were much weaker than the ionic bonds in sodium chloride, so how do they overcome the ionic bond strength? Do the ions simply get swarmed with enough water molecules so that the combined dipole interaction forces break the ionic bond? Or is it possible that because the sodium chloride dissolution reaction is endothermic the hydrogen bonds on their own are not enough to break the ionic bonds so the reaction must draw energy from the surroundings to do so (the reaction must be entropically favorable to do so, right?)?
