What do we call reactions that involve an exchange of one or more ionic components?

Reactions that involve an exchange of one or more ionic components are termed "exchange reactions." In these types of reactions, the ionic components of the reactants trade places, resulting in the formation of new products. This typically occurs in solutions where ions are dissolved. For example, when two ionic compounds react in an aqueous solution, the cations and anions can switch partners, leading to the formation of different ionic compounds.

Exchange reactions can be seen in various contexts, such as in double displacement reactions where two compounds react and the ions are exchanged between them. This contrasts significantly with redox reactions, which involve the transfer of electrons, or decomposition reactions, where a single compound breaks down into two or more simpler substances. Combustion reactions occur when a substance combines with oxygen, typically releasing energy in the form of heat and light, but they do not primarily focus on the exchange of ionic components. Therefore, exchange reactions accurately describe the process of ionic component exchange.
