Dissolving ionic compounds in water When an ionic compound dissolves in water two processes occur 1. Energy has to be taken in to break up the lattice and separate the positive and negative ions. This is the lattice enthalpy 2. The ions become surrounded by solvent and bonds form - energy is released when these ions form bonds with water molecules.

Many ionic compounds are soluble in water, however, not all ionic compounds are soluble. Ionic compounds that are soluble in water exist in their ionic state within the solution. You will notice in Figure 7.2 that the sodium chloride breaks apart into the sodium ion and the chloride ion as it dissolves and interacts with the water molecules.
