Solubility - Purdue University We can generally assume that salts dissociate into their ions when they dissolve in water. Ionic compounds dissolve in water if the energy given off when the ions interact with water molecules compensates for the energy needed to break the ionic bonds in the solid and the energy required to separate the water molecules so that the ions can be inserted into solution.

Why do ionic compounds dissolve in water? | Socratic Ionic compounds dissolve in water because the water molecules hydrate the ions. > To dissolve an ionic compound, the water molecules must be able to stabilize the ions that result from breaking the ionic bond. They do this by hydrating the ions. Water is a polar molecule. It has a permanent dipole. The "O" atom has a partial negative charge, and the "H" atoms have a partial positive charge.
