What is a double replacement reaction?

Double replacement reactions—also called double displacement, exchange, or metathesis reactions—occur when parts of two ionic compounds are exchanged, making two new compounds. The overall pattern of a double replacement reaction looks like this:

\greenD{\text {A}^+\text{B}^-} + \maroonD{\text{C}^+\text{D}^-} \rightarrow \greenD{\text {A}^+}\maroonD{\text {D}^- }+ \maroonD{\text{C}^+}\greenD{\text{B}^-}A
