An exchange reaction occurs between compounds that, when written as a molecular equation, appear to involve the exchange of parts between the two reactants. An exchange reaction will occur when ions in solution form insoluble products, weak electrolytes, or non electrolytes.

An exchange reaction is a combination of synthesis reaction and decomposition reaction where in a sense both are occurring over the course of the same chemical reaction
