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.
