Quizplus · Accepted Answer

The reactions listed are examples of ionization (where molecules break down into ions in solution) and dissociation (where ionic compounds separate into their ions in solution). They are indeed reversible and occur in aqueous solutions. However, they are not exchange reactions, which involve the exchange of ions between two compounds.
