Difference between dissolving and dissociating Dissolving is a general term for when something is placed into a solution, and the substance breaks up to make it seem as if the substance is no longer present. This could mean that the original structure of crystals breaks into small pieces, the process would be one of dissolving and not dissociation. Dissociation is "the separation of ions that occurs when an ionic compound dissolves" (Modern Chemistry by Holt, Rinehart and Winston). An example of dissociation would be when NaCl is broken up into Na+ and Cl- ions independent of each other. Thus, dissociation is more specific than dissolving. Anything that dissociates also dissolves, but not everything that dissolves can dissociate.
